How do i do 6D
I know it’s the perpendicular distance between the two lines but how do I work that out

hey i need help with 2.6
im not sure where to start with proving this
/disproving it
wait
i think i have an idea
If you let
A= (1 0)
(0 1)
B = (0 1)
(1 0)
A+B = ( 1 1 )
( 1 1)
determinant of A is 1 and
for B
its -1
but the determinant for A+B = 0
so its not invertible for all cases

i need someone to answer my math pronlems, im running out of time and im struggling
what are the two points i can use
is that the answer
lmao no
bro
that's what i'm asking you
y-intercept happens at x=0
what is the value of the graph when x=0
i did what u said and its still not right
Recall the equation y-y1=m(x-x1), that is, where m is the slope, and (y1,x1) is some point on the line

what is your question?
This
do uk how to multiply fractions
Yeah
i think what uve to do is do that
But idk how to make them into a mixed fraction
Yeah
ok so
I’m having a hard time w it
for this u just
Wait no
The whole thing honestly
oops
wrong
How to multiply fractions?
The first step when multiplying fractions is to multiply the two numerators. The second step is to multiply the two denominators. Finally, simplify the new fractions. The fractions can also be simplified before multiplying by factoring out common factors in the numerator and denominator. Simplifying before multiplying...
$\frac{a}{b} * \frac{c}{d} = \frac{ac}{bc}$
LOL
we dont talk abt that 
ok yea u can just use khan
i'd say use khan academy
HAHHAHA YES
Ha

Hey hi there everyone. I've a question about discrete maths proofing.
Given that i have this following statement here.
p∧¬q
If i applied rules of interference for simplification, would i get
¬p /¬q
Or would i get

how do i prove the solution of that DE is this ( upper one is the DE nd lower one is its solution )
DE means differential equation
@rocky jewel
yes
what
make the question clearer pls
i edited
hmm 🤔
@rocky jewel did you look up something like proof of integrating factor os something?

good evening, how might I solve this?
what are you asked to solve?
I'm asked for the slope of the line
hmm can you identify 2 points which lies on the line
(-4, -4) and (1, 4)
perfect
so the slope of the line m is given by $m= \frac{y_2 - y_1}{x_2 -x_1}$
hmm 🤔
why si it red
,tex magic
because deep is unique 
but I tried calculating it by doing delta y / delta x and that gave me 1.5
and that was wrong
why is that
Result:
1.6
3/2
hmm 🤔

for every change in x y changes 1.5
but not quite there
enhanced

"get better eyes" - deep


yo lurker
anyways if you done then probably close?
so the method for this is to just find 2 points in the plot and then do x2 - x1, y2 - y1 the divide
yes

if I wanted to find the domain of this equation could I factor the denominator
\frac{x^2+x}{:x^2+4+3}
tan$^{-1}(a)$ is the same as (tan$(a))^{-1}$
Sorry my bad I thought the command thing would make it look different the problem looks like this

I dont understand how to do this or the relevance of orthogonality
If they're orthogonal, their dot product is 0. So (2u + 2w)w = (2uw + 2ww) = (0 + 2|w|^2) = 8

How do you do this? I thought mv^2/r = Bqv would do the job but it’s wrong
Yes
So the centipretal force is magnetic field force + weight?
Idk, I’m just hypothesizing
Okay lemme try this
But how will I figure out the speed chase now I have this
mg+Bqv=mv^2/r
Oh right
@grave thistle weight would matter here right?
idk xd
Also @shrewd basin I’m not entirely sure abt this, but wouldn’t it be Fb-Fg instead of +

I have to find whether function is even or odd. It is odd according to sol, but idk how to arrive there
The f is: y = ln(x + sqrt(x^2 + 1))
I know about raising -f(x) to -1 but i cant arrive to f(-x)
its odd
yea it is
But how to arrive there
What is f(-x) ?
-x + sqrt(x^2 + 1) is 1/x + sqrt(x^2 + 1)
What is -f(x) ?
It is: ln(-x + sqrt(x^2 + 1))
forgot the brackets
Dis one is
yea nic and ln(1/x)=-lnx
-ln(x + sqrt(x^2+1))
Yup
Rationalize the fraction in the ln
ok so u got f(-x)=-f(x), and that is the defination of odd function
Ikik
um
Before / is on top
After / is on the bottom
I am on the phone its a bit quicker this way
No
The denominator should cancel down to 1
U r right
Wait a sec
Alright now I am on PC
It's easier to type here
So
It cancels
and I get
ln(x - sqrt(x^2 + 1))
I don't see it
Should be x^2-(x^2+1)
And now you are left with ln(-x+sqrt(...))
Which is just f(-x)
So f(-x)=-f(x)
And we are done
Ah
I see
So the rationalization part
Is the key to solution
Good good
Thank you very much!

does anybody know how to solve square roots and stuff like that? im having a lot of trouble understanding it
is sqrt(5)>3?
is the square root of 5 greater than 3?
are you sure?
no
No
idk what your asking me
bro don't answer it
i'm not asking you
im asking bread to think about it
My bad didn’t scroll up 
i think so
Just raise both sides to the power of 2
3^2 = 3*3 = 9
sqrt(5) = ?
what is sqrt(5)^2
That's quite a big number
is itr just 5?
Correct!
good
and is 5>9?
no

I am confused on identifying applying the first derivative test and the second derivative test.
Wdym ?
context
For example like more precisely the points of inflection
???
just post the actual problem
ye lol

When a function is inside another function
In this example: x-pi/2 is inside sec(x)

The answer said it's y+x
But how?
It’s (x+1)y -x(y-1)
I thought that but is it always necessary to put x in front?
It doesn’t matter the point is you have the brackets
So when you distribute the minus sign
You’d get -xy + x

hi can someone explain to me why did they let y = t when a != 0?
hi
wat
sad
yes
yes
eh
its just
using an arbitrary dummy variable
kinda like
the
span of solns ig?
when u were working with matrices
u kinda just use a dummy var too
ohhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh
thanks
ok thanks pro math person
cult stuff
LOL
wats wrong

.closie
okay madam
nani
send an incomplete
from ur mom
nihao
no im busy rn
NANI
ill wait till u un-busy urself 🙂

hi
name a few ways of cooking pasta
use a plate
WOW
and hotdogs yes
u arent
and eggs
good boi/girl
yay
OK SO
we wanna get from
the explicit form
to the implicit form
wtf is it doing
yes
lmao
it seems like
explicit form is just
writing the eq of a line
in parametric form
so
yes
yes
yes
made t the subj of the eq
from the first bit
like
omg
isnt the
ans
super straightforward
i dont get
what u dont get
like
i feel
im repeating verbatim
the point
(2+5t,3-2t)
is
(x,y)
we equate the 2
2 get 2 equations
then we made the subj of the eq t for both
then as weve 2 equ of
t= stuff
we equate both stuff
and rewriting it we get our implicit eq
like
idk
thats all ig?
hello
which bit
after the =>
idk
2x
nani
the
we just
YES
play with the equation on the left
omg
omg
i feel stupid now
why
sorry mother

yes
HAHHAHA
what type of eggs
LOL
i just dump the eggs inside
try
let it sit there
oh
i used a spoonful of salt

whats r
wat
im doing that
but
im
taking out the cream
cream is
unhealthy
im just gonna use
eggs n cheese
HAHHAHA
ok so whats the issue with this
i had to put alot of water
so whats r
the origin
no
a is also an arbitrary pt on the plane
its like
imagine
on 3rd
aka in front of u
lets say like this
where u r the origin
looks so ugly as well
idk what the diag is saying
ok
ignore the diag
ok so
imagine u r the origin
i mean
the world revvolves arnd u after all
thrs
thrs some like
yes
is the line ap
wat
a plane that goes thru the origin
r is a plane?
well
more like
it can take on all values on a plane
then
r-a is that but the plane goes thru the origin
anw then what
ill add pasta to water now
hi


let me continue reading
u can eat ur pasto
yes mom
r u alive
yes
hi
hi
wirh
so here
wait
wat
ahh
wow
why do u know how to cook
