[vale rock]

Hello, did you try solving it?

[warm wigeon]

i really cant do proving

[vale rock]

You should learn its one of the satisfiying part of mathematics

[warm wigeon]

omg this is such a big help 🥹🙏

thank you so much

[warm wigeon]

i definitely will 😞😞🙏 thank you

[vernal raven]

@warm wigeon has given 1 rep to @vale rock

[vale rock]

Np but try to solve such questions it will help you in exams

[warm wigeon]

i hope i can ... i have upcoming pre calculus exam in 3 days 😢😢

[vale rock]

Oh good luck with it even I am doing pre calc right now in uni so i can feel wht your going through

[warm wigeon]

thank you 😭🙏🙏🙏 A LOT ure an angel i love discord

[vale rock]

Your welcome let me know if you need help in future

[warm wigeon]

are u still gon be the one answering my future questions 😢

[vale rock]

Sure but i am out right now so it will take around 20-30 mins for me to reach back home

[analog kite]

I am back home but I cant access my other account for some reason lmk if you have anymore questions

[raven palm]

proving trig identities is
apply random identities around until you magically get the right side !!!

so just try random stuff :D

[warm wigeon]

hi @analog kite @vale rock

which 2 of these problems r less harder to prove

[pure briar]

that looks fun to solve but uh maybe ill answer after a while

[night pilot]

omg these are so fun to solve

[warm wigeon]

@pure briar @night pilot can u guys help me w that 😭😢

i just need to choose 2 problems out of all

[warm wigeon]

btw thank u for this, only a few of us in class answered & passed our homework so we who did automatically got a perfect score 🙏🙏

[vernal raven]

[night pilot]

when do u need it by?

oh wait i read it wrong

[night pilot]

honestly

for these types of questions

it’s kind of subjective if it’s easy or hard

it’s based on how well u personally know the process

trust ur intuition id say but maybe 1 and 3???

[analog kite]

1st one is very easy

[analog kite]

Np

[analog kite]

2nd and 3rd one are also easy @warm wigeon

5th one

[warm wigeon]

i need to pass it on dec 18

[warm wigeon]

i honestly dont have time to learn our pre calc topics rn bcos i have so many other subjects to focus on too 😭

but thanks for everyone's helpp

[analog kite]

I have a cheat sheet for trig identities if you need i made for uni use but it might help you

[warm wigeon]

oh my gish thank u smmm!!!!

[vernal raven]

@warm wigeon has given 1 rep to @heavy snow

[analog kite]

Your welcome

[night pilot]

don’t learn it

just memorize the process

and do several problems

then ur brain will just know how to do it

[night pilot]

that’s not bad

HUSTLE

[pure briar]

im back 💀

will solve this in a moment

[analog kite]

Ngl one of the worst ways to do maths

[night pilot]

long term yes

but short term

u do what u need to

you’ll have to relearn it later on when ur in a higher math anyway

like i forgot the unit circle

no prob

i memorized it again

[analog kite]

ngl i am gonna do this in my end sem but i doubt they will give such questions

[pure briar]

anybody done the 4th one here?

[analog kite]

I think i did

[pure briar]

im kinda getting the numerator but with -2cos

[analog kite]

let me check

[pure briar]

at the end

we can sort it out as 1 + cos/1 - cos

but numerator gonna have negative 2 cos still

[warm wigeon]

how can ppl be so good at math 😔 😔 i feel so dumb here

[pure briar]

bro

honestly

a good tip is to convert everything in terms of cos and sin

but when u feel like u can apply an identity then do that

[analog kite]

let me try to do it

[pure briar]

ok ok

ill try it once more

[warm wigeon]

i cant even do that omygod pls dont judge me ik im stupid

[analog kite]

i think i got it

[pure briar]

the "instincts" will develop with practice

practice is all

[pure briar]

care to share?

[analog kite]

Try to multiply and divide the LHS with 1-cosx

[pure briar]

huh

1 sec

if i do that im gonna get 1 - cos

as the result

wait

yea u gotta divide too

mb

[warm wigeon]

thats what my teacher said earlier too hahahaa i def will 😔

[pure briar]

no but im serious

I sucked at maths too

[warm wigeon]

i dont think i can move on to basic calc next sem im gonna die

[pure briar]

kinda got fed up of people telling me all it takes is practice

[pure briar]

but uh honestly that alone imo is the answer

[warm wigeon]

thx. ure an inspiration

[vernal raven]

@warm wigeon has given 1 rep to @pure briar

[pure briar]

oh yea

u rationalised it

that slipped over my mind

[analog kite]

Practice and keeping the basic topics clear

[pure briar]

yep

[warm wigeon]

yo is this an answer to no.4

[analog kite]

yup

[warm wigeon]

ahhhhh thanks!!!!

[pure briar]

its a bit of trial and error too right

[analog kite]

our prof told us you can go do 1000 different type of questions but if topic is not clear then he can give a question which u cant solve

[pure briar]

in trigono

[pure briar]

yeah of course

[analog kite]

mhm and thats why when you have LHS and RHS you should try to read both ends first and try to have a clear picture in mind as to change what exactly

[pure briar]

pretty much

thats what makes trigono fun tbh

It's like solving a puzzle

[analog kite]

true

[pure briar]

however I've probably only done it at a basic level

identities, ratios and all

and its applications

[analog kite]

I mean any topic of maths is fun for me

[warm wigeon]

dam

[pure briar]

personally i find statistics kind of boring

it can get lengthy

[warm wigeon]

is statistics hard

[analog kite]

you should look into euler formula if u didnt

[pure briar]

It's not

its actually kinda easy

[warm wigeon]

i dont trust math ppl

[pure briar]

I've heard about that

[pure briar]

nah really lol

im not a math nerd

I'm an average kid

[analog kite]

It gets hard if you go deep into it on surface level its not that hard

[pure briar]

really?

[warm wigeon]

okay ... i rly cant trust ppl good at math saying its ez

[pure briar]

In my school we've done median, mode, mean, cumulative frequency graphs, histograms, polygon graphs and all the other basic stuff

[analog kite]

Yup advanced stats is harder

[pure briar]

I think im gonna start ogives next year

[analog kite]

Thats easy part of it

[pure briar]

yea ik

i mean im just a 10th grader rn lol

[warm wigeon]

dang

I FEEL SO DUMBBBBBB

[analog kite]

Good luck

[pure briar]

what grade are u in

?

@warm wigeon

[warm wigeon]

IM IN 11TH GRADE

[pure briar]

Board exams.

[pure briar]

I see

[analog kite]

Its fine guess what I learnt trig properly like a few months ago

[warm wigeon]

and ure so good

[analog kite]

What stream are you gonna take after boards pcm?

[pure briar]

non medical

[analog kite]

nice lmk if you need help with anything

[pure briar]

thanks senior

[pure briar]

definitely not gonna be easy lol

[analog kite]

nah its just these french questions they force you to think out of box

[analog kite]

its not

[pure briar]

I know

rip sleep

[analog kite]

in uni its even worse

[pure briar]

yeah man i know

lol

[analog kite]

11th 12th u still get some sleep

[pure briar]

hope u dont suffer too much

[warm wigeon]

fr

[warm wigeon]

ure scaring me

[analog kite]

I dont suffer much cuz i find my degree interesting

[pure briar]

yeah lets not talk about this depressing stuff lmao

its reality but still

[pure briar]

good to know

[analog kite]

if u like what you take as ur major its gonna be nice

but hectic

[warm wigeon]

alright

[pure briar]

I have my biology exam on 13th

tbh i hate bio

[warm wigeon]

good luck!!!

[pure briar]

thanks

I had a physics exam today as well

in fact i read ur trigono questions 30 mins before the exam started 💀

[warm wigeon]

dang

[analog kite]

if you guys want to practice trig here is a question not that easy but not that hard

[warm wigeon]

r u good in physics as well

[pure briar]

I am decent

but i am definitely better at maths

[analog kite]

Newton's laws?

[pure briar]

nope. magnetism, electricity, human eye and light reflection and refraction

all that stuff

[analog kite]

i still remember studying human eye lol cornea, retina and stuff

[pure briar]

yea

eye diagram is easy

the whole eye chapter is in fact

[analog kite]

mhm

[pure briar]

light refraction and electricity is where the main stuff comes in

[warm wigeon]

how r yall so smart 😅

[analog kite]

I am the guy who starts to study 1 day b4 exam

[pure briar]

I find it funny how you call me smart yet the kids in my class think of me as average (in context of my class I am)

[analog kite]

ikr

[pure briar]

theres this girl who literally knows everything

like she will always answer the teacher

always

i cant even remember when she didnt lol

[analog kite]

in our class we had ppl score 20/20 and i got 11/20 just pass

[pure briar]

yeah well

[analog kite]

but then only 14 ppl passed so i am chill

[warm wigeon]

ok then im just very stupid

[pure briar]

that girl scored 79.5/80 and the teacher cut her half marks because she said "its not possible"

LOL

i hate that teacher ngl

[analog kite]

ok now time to go study for my finals just ping me if u guys need help

[pure briar]

ok ok

[warm wigeon]

i wish i was her

[pure briar]

I'm gonna go sleep I guess

[warm wigeon]

thx a lot guys

[pure briar]

u can become like her but just wishing u were like that wont help

remember

[pure briar]

np

aight bye

[warm wigeon]

okay : D

[torn jackal]

which application bro?

[analog kite]

Good notes 6

[torn jackal]

u got the answers?

solve 1 and 3

[warm wigeon]

okie

[raven palm]

haha

[raven palm]

well what did you do

[warm wigeon]

im embarrassed to show 😭

[warm wigeon]

how did cosθ/sinθ turn to (1+1/sinθ) ?

[sharp venture]

they factored out cos(theta) in the denominator

[warm wigeon]

thank you

[vernal raven]

@warm wigeon has given 1 rep to @sharp venture

[sharp venture]

urwelcome

[raven palm]

is that for the last question lmao

[raven palm]

cuz this is just cot^2x

[bronze plover]

I did the first one

[analog kite]

you dont need to do all this just replace secx with 1/cosx and cscx with 1/sinx and you get to cos^2x+sin^2x which is 1

[olive field]

instead of solving the problem for OP, you should give guidance/hints, and let OP do the work

[pure briar]

this thread is still up?

[analog kite]

for some reason yes

[pure briar]

I see

longest one yet maybe?

[pure briar]

I think this can be solved in a different way btw

actually just the same method but has more steps

[analog kite]

mhm this is wht i do too generally

[warm wigeon]

thank youu

[vernal raven]

@warm wigeon has given 1 rep to @pure briar

[warm wigeon]

im finally done w first sem thanks to u guys

[pure briar]

good luck

[analog kite]

Yo thts nice i still have finals

Then i change to physics

[pure briar]

my test series are almost over

just 5 more days

[warm wigeon]

GOOD LUCK EVERY1 💗💗💗
