I can't think tonight or something

Why can't I get the right answer :(

-3, 2, 4 was what I last tried and it told me it was wrong. I tried -3, 4 as well.

nevermind I figured it out.

f*ckin -2 was being an invisible ninja

I should not try doing math late at night, I get stupider.

oh god why are people actually using those stupid online homework applications. is it really too hard for college professors to collect pieces of paper

why waste the paper?

i prefer online homework

I like online homework better to.

I like online homework because it tells you right away if you got the wrong answer.

you're all dumb and wrong

really buckwheat?

:)

what happened

Tim became a conservative

Uh I actually have to read my math textbook for once, I don't know about arccosents, arccotangents, and arcsecants at all.

i agree with god

We don't even have the concept of that here.

We get assignments emailed to us, but we still have to write them out and hand them in.

also people will still use paper to work on the problems so i dont want to hear this saving trees shit, i also want anyone using that argument to calculate the increase of energy expended due to larger electronic usage.

also these programs cost money, money that could have been put to use by universities to retrofit buildings for better environmental efficiency.

so there is literally no benefit to online homework at all, plus its annoying to have to type involved mathematical expressions online and they're too finicky about exact form

My school does not like hard paper work. Very rarely have I ever done work offline.

Speaking of math work, I have quite a few problems that are bothering the hell out of me:

Let f(x)=3x^5+x^3+1, find f^-1(5) (deceptively simple looking)

arcsec(-(2sqrt(3))/3) (the fucking answer should be pi/3, but its not)

cos(arccot(3/4) (there is a whole series of these, I think there is a trick I am missing, there is no regular radian for 3/4)

arccos(2x)=arcsec(2x) (idk no matter how I look at it it doesn't work out)

write in algebraic form: sin(arcsin(8x)) (again a whole bunch like these, idk)

i dont know why americans use arcsin. sin^-1 (sin inverse) is a better representation.
