It doesn't make sense as written.
It says the heading from B to the fire is NW (which would be in the exact same direction that B sees A!), but the diagram shows it in the direction 60° left of north -- that is, 15° left of NW.
Similiarly, the text says that A sees the fire in direction NE, but the diagram claims it's 50°, which is five degrees to the right of NE.
can somebody help me with my maths assesment. Its on proving continuity and smoothness
hey folks, i need a little help with parametric equations in desmos. i've made the functions, and they do in fact trace the desired shape (an equilateral triangle with side lengths 2) yet typing in the functions of t does not produce the desired shape, and instead bounces around within a rectangle
can you show what that looks like
like what you are typing and what the expected vs actual output is
sure, uh would you be able to vc momentarily?
no sorry
@worn gorge
🙏
We call that lissajou curves and these are parametric curves
hey guyss!!~~
im in grade 7 but i want to study higher level geometry for future plans. can anyone suggest where and which topic should i start from?
It depends
Wym by higher level geometry
Euclidean? Coordinate? maybe Space
i mean secondary and higher secondary level
both
I would suggest starting with triangles, orthocenter, centroid, midpoints and other properties related to triangles
Then move to circle
i already did those
Oh
kid these day so efficient, okay try circle then
Learn some theorems about circle
I have no idea what their name are but I guess you could find some in youtube
In general you should just grinding problem and analyzing it
whats that?
Coordinate related to algebra so if you have strong algebra skill that would be helpful
hey im pretty shitty in algebra😅
And also about euclidean geo skill, you'll need that to simplify the problem
i have ig problem in functions,and mathematical induction
ehh
Probably you'll need algebra and euclidean geo skill for coordinate geo
that's it
But people usually overlook euclidean geo
im pro in euclidean geo😎
das true
im saying cuz i fing geo a lot easier to solve and understand than algebra
and i really wanna attend some int. competitions
This would be the least nasty thing you would see if you're in competition
So get yourself ready
ooof the fig looks like its gonna scramble my brain but whats the question?
Couldn't find it lol
is it related to the above pic?
yeah
kk wait
did i get ts correct 😭
That's a confusing diagram indeed. It doesn't even finish the task but constructs just one angle bisector (line BG) -- though it goes some of the way to construct the next one (by drawing line BE).
do u have a compass
Hey uh quick question, why do teachers feel the need to NOT put the notes for any subject (physics) online???
Because Physics is quite frustrating at times.
My teacher literally post the answers for us, not for us to teach obviously but to check our work, so idk about your teacher, plus we just started a new unit we got done with gcfs I failed it's rough I have 3 math classes and failing all of them but it's ok I'll just keep studying but they Also changed our grading scale so that's also a huge problem for us because we're new to it.
I hate when they change the grading scale for stuff.
why do you have like 10 triple em dashes in front of your name? 😭
question.
AB and AC ar two chords of a circle of radius r such that AB = 2AC. if p and q are the distances of AB and AC from the center of the circle then prove that 4q² = p² + 3r²
How the hell do i do it
diagram from my knowledge.
Hello, can you help me understand this problem, please 🥺 ? I calculated the diagonal in the worst-case position and got sqrt of 48. I now know it's the correct answer, but I don't understand why that's the case.
Like how I can proof that it's maximum
Choose 2 points A,B on the rectangle with dimensions m and n
- If 2 points are on the same side that means AB< m or AB<n
- and two others case as shown
ehh the first one is AB< A1C1
My mistake
So the largest distance between 2 points is AC, the diagonal that makes it the worst position
Okay I think I get it, thanks
someone help me with this please
what have you tried?
I wonder what are the way to do that problem only using area
(I recognise it from some IGCSE textbook)
Really?
I'm asking my UK friend to do the problem rn
Danggg
it's already been done a lot of times online
What if you try to subtract the area of the top left corner from the area 100 - 20π?
Wait what. 2 pi?
No wait it should be 20pi.
Yeah 20 pi.
You'd also need to subtract the two small "triangular" areas along the edges.
Definitely possible, but I expect the result to be an ugly mess of square roots and arctangents either way.
yeah the answer is ugly
i would just use coordinate geometry gng 😭
you can get a start by labelling the centre of the circle, one of the intersections, and the bottom-right corner
if you think, you can figure out all 3 side lengths and hence use the cosine rule for the angles
My gut feeling is that the least painful way to get through is probably to view the shaded area as a difference between two circular segments, once you have the angles.
yeah i probably wouldnt be able to figure out any elegant way to do it
i would just bash calculus at it by integrating the small circle equation and subtracting that with the integral of the quarter-circle equation to find the one of the two small areas at the sides
if this comes out for an exam im cooked
it's a grade 10 'challenge problem'
from a textbook
basically someone watched too much Prosh Toadwalker on YT
wtf bro literally my solution of finding the intersections and integrating takes less time than this prob
although i havent read it yet just looked at the length of it
cause the coord geo took a little while
this is quicker
I found the the distance from the corner of the square to the centre. Which is 10√2/2 = 5√2. Then you have to draw to isosceles triangles. Then use the cosine rule to find the angle of the triangle but I know it because I study extra but like people in my class don't + we didnt study trig yet so...
yea it is my from IGCSE / O level Addition maths textbook
bro im so lost can someone help me i have tried so many times but i still struggling with understanding
Is the rotation of co-ordinates 90° or 270°
??
Area of square- area of sector
100-78.5
21.5 sq cm
Which grade is it
Damm
Why so much
That's not the right answer bruh
And I don't think this's the right method either
aprox
The difference is two numbers. I used rounded decimals. If I were more precise, I would have been closer. The procedure is correct.
Ohh shit i excluded the other part
Didn't see where the whole blue part was
Yepp it isn't
I didn't see what the blue part was covering
Given a circle and points A, B, and C on it, which do not form an isosceles triangle. For every point P not in the set {A, B, C} on the circle, let A_P, B_P, and C_P denote the intersection points of the tangent at P with the tangents at A, B, and C, respectively.Prove that there are exactly three points P not in the set {A, B, C} on the circle such that the points A_P, B_P, C_P exist, and the perpendiculars erected from A_P to the line segment BC, from B_P to the line segment CA, and from C_P to the line segment AB are concurrent (meet at a single point).Furthermore, show that these three points P form an equilateral triangle
Pls help me

what, sort of, fun geometry questions can one come up with? I'm starting to realize how boring my knowledges of it are, now that I'm creating questions for the pop quiz
I'm not talking about the regular "solve this, solve that" type questions but more focused on theory. an example of mine: "Pythagorean Theorem is a special case of Law of ... rule."
w polytopia
I'm so bad at trig it hurts
If I quizzed myself id get like 0% lol, mostly because I can't memorize the unit circle to save my life
Now don’t say that
if i believe so. I got the answer.
i can try help but it would mostr likely be wrong
so look.
First we calculate the number of rows and columns.
(a row is the grid of triangles you see)
which are connected to each other by edges.
the ones marked in blue is the length of the row and the ones in red are the columns.
better one
😭
here the rows are 9 and columns are 5.
And since the longest distance to the shaded tirangle is the length of red and blue
?
no that is going in my screenshots
wh
yes.
alr
yeah
W english
L speed
if my english teacher saw that she would made me a half piece
half piece chicken nugget? 😭
i love math in general tbh
tbh geometry is easiest shit
you just think and find a solution
I love math in general too
but i dont help people her
like ill learn the basics of every mathematics i come across but not touch history until its exam time 💔
cuz we didnt saw square root or stupid symbols
or atleast ill try to

ok
-# I've just found this interesting problem, so I sent it here for anyone wants to try
Fionna The Unemployed
💀
Obviously, one should draw the lower tangent lines from A and K (or B?) and find their lengths, then add them to the arc length in between.
Yup
Tbh Im not even sure how to explain that's the shortest
Welp that's the whole idea, it should be easy for anyone wants to try now
ok i missed to consider that the arc length may be shorter than if you would let the tangent lines intersect
so yea, the derivative is involved when you differentiate the circle equation to find the tangent line
i rely on derivative so much, idk if there's pure geometry to find the tangent of a circle. I'm sure there is since i remember learning a formula for it
ig any geometry formulas can be derived with calculus anyway
it's very tedious
oh yeah
Yes
Distance formula
$\frac{ |ax_0 + by_0 +c|}{\sqrt{a^2+b^2}}=R$
Fionna The Unemployed
If the distance between that line and the center is equal R then it's a tangent

So easy
hello guys im having trouble with this
loki a little confusing
my answer was x+3, y+-3
if someone is on can they help?
Seems like you want to check where your points end up after the reflection
If it reflects over the x axis that means the points go as follows
A'(-5,-2), B'(-4,-4), C'(-2,-4), D'(-1,-2) (Before translating)
After that
I'd check one of the points and then see what I'd do to it to get it where it needs to be
It's easier than checking the entire thing at once, mb forgot to reply first
acellus nice
hi there's this solid geometry/mensuration question could anyone of you help me I'm very confused😭

Ive read AOPS part on ellipse but I wanted to read more high level content... like line with ellipse and other juicy stuff... but other books dont teach stuff on problem solving they;re just slapping me with proofs... I get it that proofs are super important but I also wanna know the stuff intuitively...
Any help, even a lil bit is helpful
are there books for students trying to learn for engineering college and involves all of algebra, precalc, counting and calc necesarry in advanced levels? like super advanced and gives intuitive understanding like aops does?

Consider reflecting $ED$ over the internal bisector of $\angle AEC$.
Civil Service Pigeon
peculiar question but seems like youre just supposed to prove or disprove the equivalence and plug in the values for n and m you get from 78 and 18 in the process
what have you tried? have you tried converting everything to sin and cos?
how would you even know what to sub in for m, n
you can get to $\frac{3\left(\sin18\right)\left(\sin78\right)+\left(\cos78\right)\left(\cos18\right)}{\sin\left(94\right)}$ so that's the denominator sorted
south
a similar example would be like prove cos(90)=2cos²(n)-1 and find the value of n
the question is very strangely formulated
but i think thats it
but you clearly have two variables m, n
I fail to see how cos(90)=2cos²(n)-1 would be similar in any way
the answer would be n=45 in this case
if u do the identities with the given values ull get an expression where n and m are some values and those are what youre supposed to multiply
How do you arrive at this
do this
did you actually figure out m, n for this problem?
just want to check what you meant by 'n = 45 in this case'
i can give it a try in a bit
if no progress has been made
I'm getting this
yep, and now use product-to-sum on sin 78 sin 18
I've figured the whole question out btw
and yeah I made an arithmetic error, should be sin(96) ofc
Am I supposed to be getting this?
no, should be $\frac{\cos 60 - \cos 96 + \cos 60}{\sin 96}$
south
yep and remember the form of the answer is $\frac{\tan n + \sin m}{\cos m}$
south
On using sin a+b and cos a+B, I'm getting this. So can we assume the m and n can be either 60 or 36 as those are the only 2 values of angles?? In that case the product would be 2160
you're on completely the wrong track
go back to this
Okayy
you want to convert sin(96) to cos of another angle
no, you should get cos(-6)
but then cos(-6) = cos(6)
Ohh ok
and then same thing for cos(96); can you convert that to sin(something)?
well, -1 * sin(something) actually
it's this
sin(-6) = -sin(6)
the identity is cos(x) = sin(90 - x), sin(x) = cos(90 - x)
Yeahh got it
and then that also implies tan n = 1
So n is 45 then
yep
oh thats what u meant
didnt have time to do the problem rn but that was a funny coincidence
lmao
you made me think you solved the problem already
Is m=6 then?
yeah
it's $\frac{\tan 45 - (- \sin 6)}{\cos 6}$
south
Yeahh thank youuu
no worries!
Someone please help me with 10th question
Consider writing 3x as 2x + x
I did that but don't know what to do from there
compound angle formula
sin(2x+x) = sin(x)•cos(2x) + sin(2x)•cos(x)
My bad
that's okay!
I wrote it correctly in my notebook though
cool, so if you now use the formulae for cos(2x) and sin(2x)
that's correct now yes
So I substitute them?
you'll get closer
you'll also need sin^2 x + cos^2 x = 1
yes
I tried doing all that but got
3sin(x)•cos(2x)
how did you get that?
I substituted the sin(2x) and cos(2x) formulas, got till
3(sin(x)cos²(x)) - sin³x
And then took sin common
are you sure you're using the right formuals
you should get $\sin(x) (2 \cos^2 x - 1) + (2 \sin x \cos x)(\cos x)$
south
After that
I got 3 sin(x) cos²x - sin³x
oh okay, that's correct
you can stop there, but if you now use cos^2 x = 1 - sin^2 x
you can get a neat formula for sin(3x)
I took sin common, and got
sin(x)(3 cos²x - sin² x)
ah, and then 3 cos^2 x - sin^2 x is not a formula
only cos^2 x - sin^2 x = cos 2x is
?
you can't simplify 3 cos^2 x - sin^2 x
Isn't this correct tho?
but that's correct, yes
if you don't show your work it's hard to check
My work in notebook is a jumbled up mess so I'll try to type all of it here
sin(2x + x) = sin(2x)•cos(x) + sin(x)•cos(2x)
sin(3x) = (2•sin(x)•cos(x))cos(x) + sin(x)(cos²x - sin²x)
sin(3x) = 2 sin(x) cos²(x) + cos²x sin(x) - sin³x
sin(3x) = 3 sin(x)cos²(x) - sin³x
taking sin common on the right side
sin(3x) = sin(x)(3 cos²x - sin²x)
Correct?
ahh that makes sense
yes, that's correct
Tysm
no worries!
How is the solution of this?
Hello, I am peruvian, sorry for my bad english
anybody got (probably) the best trig cheat sheet? i imagine it's just some MASSIVE pdf with hundreds of identities or something idk
discovered wiki on trig identities
hey
I guess this would be helpful.
Note : this sheet includes the most essential ones!
Probably not a pre-university topic, but there's no "university geometry and trigonometry" channel, so:
What's the angular diameter of something at distance = 0? Is it just the diameter of the object?
Or is it infinity
Sounds like that would be very context and purpose dependent.
I'm trying to make one sphere at a different distance from another sphere appear the same size as the other
So I figured I'd do that by finding what radius would make their angular diameters the same
I can manipulate the radius of one of the spheres
But now I'm having to store the current radius of the resizable one, the original radius of the resizable one, and the last distance from the observer
I'm trying to get it to be an equation based solely on the new distance and the original radius
I would tend to say "angular diameter" is a concept that stops making sense as the distance approaches 0.
If you're thinking about camera perspective, when the distance becomes small compared to the scale of the object itself, its image gets more and more distorted, such that how it looks is not just a matter of scaling a common picture to the right size.
Yeah
Got that last bit wrong it's r1*d2/d1
But then you get here and it's like
This is for like a space game, instead of actually placing the moon like millions of miles away I place it one mile away but really small
it wouldn't really make sense for the distance away from the center spherical object to be less than the radius of that object
But the "fake moon" needs to change size based on the observer's distance to where it should be
Yeahhhhh
otherwise you'd be inside the object and need some other calculations for how that works
I mean I kinda figured that when I had to divide by zero lol
it's also apparent from the fact that the domain of arcsin is ≤ 1, i.e. dist ≥ d/2
at a distance exactly equal to the radius of the sphere, the formula predicts an angular diameter of 180, which is the entire forward vision
I just feel like there's gotta be a way to make it where you only have a) the original radius of the fake sphere, b) the actual radius of the real sphere, and c) the new distance from the observer as variables
Rather than having to store the old distance from the observer and the current radius of the fake sphere too
I'm resizing the fake sphere based on a scale factor from its original radius 1
Idk maybe I need to start from the beginning, idk if the whole problem makes sense from y'all's perspective
That is, if you're willing to help with it. Kinda getting off topic from my original question
Actually I don't think the "scale factor of the fake planet" matters cause the original radius is 1
For this equation bluh
I've confused myself so hard
Wait a second I swear to god is it just fake_r1 = fake_dist1 * fake_r0 / real_r0
I don't know ;_;
I'm a grad student I do ODEs why am I struggling with basic ratios
Any help guys
how do i prove cos(pi/n) is irrational for n>3? could someone give me a hint
2x+18=94
x=76/2=38
okay
I also use that system, so lets see
Rectangles A, B and C are all the same shape, just different sizes.
For A, the width is 4 cm and the height is 2 cm, so the width is twice the height.
That means every rectangle is twice as wide as it is tall.
The total height of the big rectangle (C) is 2 cm + 4 cm = 6 cm, so its width has to be twice that.
So, y = 12 cm.
-# Made by Math-Problem-Solver-V16.py 🙂
Would it not be 24? The width of c is twice the length of a plus the width of b, which is 2+(4*2)=2+8=10 which means the width of c is 10, so doubling for the length gives 20, remember to add the 4 of the length of a since y includes that and you get y=24
Like
In general 2a+5b=y, (a=2,b=4 in this case)

Trigonometry and geometry is not the right channel for a problem about perspective and angles?
That question ain't for studies
Definately use #chill
where does it mention that one can only ask questions about homework problems assigned by a school?
That question is completed based on prediction
Gaming
Not fun dude
Anyways...
@wintry loom The left edge of the center wood block is 200px tall. While the right edge is about 140. Typically, the way perspective works is that each block will be similar to the next down the line, so we find the ratio 200/140 and we assert that this ratio will be held for each block down the line. So the first orange block will be 140/x, where 140/x = 200/140. In other words, x = 98 or so. We don't need to find the heights of each of the blocks down the line, because we know that we can apply this ratio n times to go n blocks down the road, in other words, if we know the height of the last block we can work out how far we've gone.
The height of the last orange block seems to be 12px or so. So we have 12 = 200 * (140/200)^n where n is the number of total blocks in the hallway (including the first wood block), solving this using WA we get 7.88, or about 8 blocks total.
Hope this helps.

What is Fundamental Identities?
which topic are you learning?
Trigonometry
right, then you're looking for fundamental trig identities
I'd say the most important one is the Pythagorean identity: $\sin^2 x + \cos^2 x = 1$
south
Got it, thank you
no worries!
I’m taking a trigonometry, I can post some notes and questions here for help?
yes
Can someone friend request me if u can help with verifying expressions in a call please
I can’t figure out D
Hi! Is there anyway you could rewrite this term?
Hint: Multiply the top and bottom by something.
Actually this is overkill
Did you try combining the fractions?
Yes this is what I got
Where did the sin^2(x) go in the numerator?
Omg I forgot it
It's basic
Oof
Your expand is incorrect
There should be sin² in numerator
Are you guys able to call or no I’m sorry i struggle a lot with math if not that’s fine I’ll keep typing
Which class ?
Trig
What identity did u use to get to 1+1+2 part
Because sin² + cos² is 1
What about the other part
Which step ?
Hold on I’m going to rewrite
In which step should I message with explanation
Why I see a square root !!
If the 2 was a 4 would it be 4 x 1/sin
Everything is correct
But I think you should mention identity used
Ignore the last part for d
I’m going to go back and highlight so I can review
Do you know how to find exact values of an expression?
I can send an example
Like sin 0 and 30
Yes I know every ratio till 90
And sin and cos till 180
Wait I don't know this exact ratio
I know like
0 30 45 60 & 90
But I can provide help
It’s okay I’m going to skip it for now
I’m going to try another one
Ok for this one which side would u start on
I’m thinking the right
Which question you are doing
Hold on
Mine one ?
Ok
Because sec isn’t in cos and sin?
But the left looks more complicated but I’m not sure where to start there
Wait if you are not getting any idea
Convert everything to sin and cos
But sec is 1/cos
Wait
This question is easy
Want hint ?
Firstly you remember all identity?
Nooo
Wait you are not doing correct
In second step you wrote sin instead of sin² 💔
It's night there ?
It’s 3am for me
Let me give you a great hint
Write 2 as 1+1 in first step don't break fraction

any proof ?
like how
how it could help in the question above 2nd part
<@&286206848099549185>
sorry i misread the qn
notice that B1C1 = 2B'C' = BC
and then do the same with the other sides
thanks
yo im studying about circles, angle measurements, arcs, central and also inscribed angles, tangents and secants
my exams tomorrow
is it possible for me to relearn all of this in like a night
im an average math guy
i think so yeah
the all circle geo is depended on rules and if you really learn them
you can easily beat ts out of the exam
dont do work by rote tho
learn them
i used to solve a few tests of easy circle questions
when i finished it i would solve hard ones
do it like this i hope you will get somewhere
Man my fooking dumbass forgot to study the week becore
Alright, i will thank you lots
if you really are into this geo thing you will do it im counting on you bro
hope you can make it
Im cool w geo just not like super into it
so real
if my brain forgets everything mid exam then it is what it is twih
youre cool man
you wont trust me
Still in g10
i was there too it really just gets in your mind
just do the study part and count on urself
Is it ok to like just stay up w caffeine for exams?
Aight aight
dont just drink 1 liters of pure filtered coffee
but a few glasses wont hurt
get a few hours of sleep tho or else you really are going to forget the things
Alright
Yeah i will bro thank you
Also w jjba ofp
türk
a^2+b^2-2ab.cosx
yo
12
yeah bro
expectations?
shouldn't have said that here
real
and if anyone is offended by this, fuck you.
i will have mental breakdown again but not in deepseek chats this time in server but no i will not show it
i am 10th grade
do i have time
for
YKS
just show
examples
questions
i am just showing example questions
math exam tomorrow barely studied
i have extremely severe adhd
will take months to get right meds
and a lot of other shit
Hi sorry if this is a dumb question but is the question I circled an acute isosceles or acute scalene? I’ve asked a bunch of ai’s for help and all of them said it was acute isosceles but the answer key says it’s acute scalene can someone help I’m so confused because I thought it was acute isosceles since there’s two congruent sides 😭
the answer keys wrong
it is acute isoceles
actually i think its obtuse isoceles
yeah its obtuse
can you explain how it’s obtuse
see the first angle is 25 right
Right
so the second the angle opposite to the other equal side will also be 25 right
Ohhhhh yeah yeah
so the thire will be 130
Ohh okok so then it’ll equal 180 okay I got it now THANK YOUU
yeah np
wiat I have another question the answer key says it’s scalene is that wrong as well?
Cause there’s two congruent sides
Ohh okok got it thanks again
Like grade?
yea
10th
alrr
Yupp lol
im also in 10th
Oohh reallyy? What math are you taking rn?
idk bro im indian i have to take whatever they give me
IM INDIAN TOO and that’s nicee im taking geometry and algebra 2 at the same time and its hard but its okay at the same time 😔
ohhh nice
if i put it in those terms id prolly say im at like precalc level prolly
wait so you get to choose not to do other stuff in math??
Ohh damnn that’s nicee is it easy?
im not actually following that course cuz we dont have that here but last time i checked the content it matched to what i know
Are you two in CBSE boards? Socrates and aash
Sometimes but for me it’s mandatory to do algebra 1, geometry, and algebra 2 after that you can pick whatever u want
Ya I do
Yeah, I was wondering from that triangle question
hmm bro atleast you dont have to do finances
Same time?
Finance seems way better I’d rather take that instead of algebra 2 😭
Yes it’s called double block math you can take two math classes at the same time but in different class periods if you know what I mean
i mean difficulty wise yeah but its so fuckin boring bro and like we dont get calculators so calculating is such a pain in the booty
damn that sucks 😭 we don’t get to use calculators either for algebra 2 but finance is a way easier class how are u complaining 😭😭
Do u stay after school or something?
No like for example let’s say first period is geometry and then fourth period is algebra 2
dude finance is boring and its so hard to understand like half the questions are ambiguous and shi but algebra is all sybolic so theres no wierd phrasing and it also feels less fake
But you are definitely strong in math or to be fair all subjects lol.
Do you replace a class or something like that
dont say all i almost failed in history and geography
Oof!
Yeah finance would seem pretty boring but for us the finance class is basically just projects they barely have any tests
yeahh and for us its like memorising every fuckin sum till its engrained in ur brain
btw whats an infj?
😭 no girl we have eight periods in total and four per a school day which get spilt into A day and B day, for example in B day your first period will be Geomtry your second period will be English your third will be history and then your fourth period would be Algebra 2
What’s there to memorize in finanace tho 😭😭 like the accounting equation or smth
It’s an mbti personality type 😭
yeah bro there r like so many formulae
why tho ? 😭 but finance is a pretty useful class it’s not required here tho
Yes it’s called mbti test it’s pretty popular on the internet
yeah it might be useful but i still dont like it
it just feels kinda fake
😭 what
idk bro
How does finance feel fake
it just feels that way
bro this test is long af
But like how 😭 ur logic is weird
It is but it’s like the official test
So take it
see like it feels like a bunch of made up formulae even though theyre not
when compared to some other types of math
That’s like every other type of math tho
Everything is made up
nahnah
bro trust other math is goated
Like why would I need algebra 2 in the future 😑
heck no finance is the only one that is acc useful 😭
Yes that one
i mean depends on your field of work + i do math cuz its fun not cuz i need it
FUN?? 😭💀
But why
How
Do you think MATH is fun
😭
That’s true tho but I wanna go into business so idk how geomtry and algebra 2 is gonna help 😭😑
bro sometimes with math i just get that dopamine after i solve a problem\
then finance is prolly right for you
ok i got entp-a
DOPAMINE 😭 but why tho is math like your favorite subject
Yeah I’m gonna take it or smth similar to it next yr
That’s like the debater personality type right
ye
Ofc ofc 😭 it’s probably my least
wait so what classes are you guys supposed to take and like what choices do you have ? not only math all subjects
We’re supposed to take English, science of any choice like biology, physics, chemistry, then we have math which you can pick, history which you can pick too like AP human geography, world geography, AP world history, then you have to take an elective which can be like orchestra, band, art, choir, dance or whatever they offer and then you also have to take a health class, speech class, and sports class
But you have lots of choices
bro that sounds so nice
so you dont have to choose all sciences?
or even like history
No not really, for example if you want to do biology you can do biology adv, chemistry then AP bio in three years
what does AP stand for
Nope you sort of just level up each grade level so you’re eligible to take certain classes
Advanced Placement it’s this type of course in high school which is equivalent to college level courses and it boosts your GPA (your average grade) a lot
Yupp in ninth I took AP human geography and AP computer science principles, rn I’m taking AP stats, AP world history, and AP seminar
It’s not that much most people take 10-15 if they rlly want to get into a competitive college 😭 so I’ll have to take a lot more over the summer or next year
but i thought these are college level course shouldnt they be difficult for someone in the ninth grade
So there’s two types of gpas, unweighted and weighted. In unweighted gpa all classes get treated equally no matter how hard they are and each letter grade is assigned a point value, like for example if your grade in math is 90-100 (A) your gpa points is a 4.0, if its a 80-89 (B) then its 3.0, ifs its 70-79 (C) then its 2.0 and if its 60-69 (D) it’ll be 1.0 and if you get lower than that you basically fail that class so you get no gpa points. So basically for example if you have 3 As, 2 Bs, and 1 C = 4+4+4+3+3+2/6= 3.33 gpa or smth
Weighted gpa is out of 5.0 or 6.0 and that’s just based on how hard your class is so you can get extra points since they’re harder
But yeah lol
yeah that makes sense
Yupyup lol
so you fail if you get below a 1.0? not an f?
Fail and F are basically the same so you’ll get no points for it
ok what about like e and stuff
What the crap is e 😭
😭 I think so cause I don’t know what that is
What is e 😭
What the crap why would u go all the way to g 😭 just end it at F
Is that a good thing or a bad thing
i went to the exam and just sat there and randomly wrote some words on the paper
i scored like 8 on 100
incomprehensibly bad
I CAN TELL 😭🙏🏽 an 8 out of 100 ?? What was the test even abt 😭
it was kanada
its a language
i was supposed to learn it but i never had a book for that so i just went their and wrote some random shi
Oh yeah ik im Tamil I thought this whole time you were North Indian
cause u gave off the vibe
i am east indian
i live in south india
nice i have many tamil friends
😭 well yeah obv ur gonna fail why didn’t u get the book earlier
Ohh mb but that’s nice what language do you speak?
i had it but i think i accidentally gave it to my friend which he never returned back so idk
bengali hindi english
i understand odiya and nepali
😭 why didn’t u ask him to give it back before the test did u forget that there was a test that day
yeah i think he came back with the same booklike 2 years later
and he was like this is urs bro
Damnn that’s nice I can a bit of Tamil but it’s not quite fluent loll which one is your mother tongue tho?
bengali
Well that’s unfortunate do you guys have re tests there?
Ohh okok nice
Yeah it is it’s nice but very hot ive been there like 4-5 times but the last time I went was last year I think have you been there recently?
in fact my dads in chennai right now
i have been there an year ago
India brother i found 😂
Damnnn really? For work?
Did you live there or did u go just for vacation
yea for work he goes there like every 3-4 months
Live
But I think you guys should go to chill chat for this
doesnt matter
Ohhh okok that’s nice I really want to go back again but were most likely going for vacation next year have you been to any other states?
hi Mild mystic

wait ill list them out karnataka west bengal uttarpradesh rajasthan maharashtra tamil nadu (want to go to northeast dehradun etc)
No they are different states
Near to Himalayas
no thyre north
Don't go to dehradun
My sister lives there for college
Go to mussoorie
It's better
really im was thinking like ranikhet koushani and stuff
also
Ranikhet you can go if you are in a group
I saw tiger there in woods 💀
Damnn that’s a lot that’s more than I’ve ever seen in the u.s lol 😭
crazyyy
Ohhh okok mb mb

Idk if u know tho 😭
just tell i might know
Oo sureee I’d like to seee
Okay tell me which states do u know

all i could think of
i prolly know more but they arent popping into my head
hmmm okok fine but you listed one of them here
ok does it start with the first half of the alphabet or the second half of the alphabet
Second half
how many vowels
It has two I think
None of those
The state has like A LOT of Indians tho
north or south?
But that’ll give it away 😭
Okay think
wahington
no nvm
wtf
u said 2 vowels
i think either new york or utah
ig newyork
Nope it isn’t
New York doesn’t have a lot of Indians I’m assuming
hmm
But you did say the answer I just said no cause I just wanted to 😭
