general

arctan of infinity is pi/2

negative infinity is -pi/2

of 0 is 0

i think

lim as x -> 1 of arctan x

or its rotated

pi/4

oh wait

I know

it is

I dont know how to do it without a calc though...

do you know the unit circle?

not really

you should

well

I dont

rip

not for tangent at least

tangent is sin/cos

so when sin=cos is when tan=1

yes

and sin = cos at a 45 degree angle

and

thats like

1 sec

pi/4

pi/4!

don't use degrees unless you have to

MATH

I DID IT

I know

I just dont have pi memorised yet

undefined

but

is it appraoching negative or positive infinity

the world will never know

positive

wait how

the numerator is positive

really

1/0

is that a shortcut?

what are we talking about?

I dont even know

lmfao

guess what i get to learn in school

I have to memorize this song

im in the highest english class they let you take wtf

are you in 3rd grade?

nope

he said he waas in an advanced english class

I mean

Advanced fourth grade xD

we had to realearn stuff like that in advanced english

ap english

Dude i dont understand why im learning this

you never use them

ever

study it for the quiz and forget it

so you know which words can be prepositions instead of learning how to identify them by sentence structure

school makes you dumber

I already have them memorized but the test isnt until friday

Welp

back to reading about arguement structures

like logical decomposition of arguments?

logical fallacies?

Both of those yes

fallacies comes much later in the course

are they not the same thing?

meh

I guess not

no
