What classes must one pass before posting on /sci/?

Goddamn I wish that my calc 2 class's problems were that easy. Thats some babby shit.
>>7716023
All of them

The ln term is just 1 (inside is the definition e)
the sin^2 term is 1
not sure about the sum, but I'm willing to bet the cosh shit reduces to 1 as well and the sum then is 2, so you get 2=2

false, lim z->infinity (1+1/z)^2 clearly evaluates to 1, and ln(1) = 0, so the first term is zero.
most of this is an exercise in trig function algebra. A pretty pointless exercise.
>>7716043
fuck, I read that as 2 rather than z, I take that back
>>7716043
It's a z, not a 2. (1+1/z)^z evaluates to e. ln(e) = 1.
Did anybody go through the last versions of Anton's textbook on calculus here? How would you rate the difficulty of its problem set from 0 to 10 (and comparing with Apostol and Courant's textbooks)?

Well judging by most of the posts on this board, I would say pre-algebra.
I haven't covered series yet, but I got the second one down to 1/2^n, and then just used wolfram to calculate it.
>>7716023
this is easy as shit

>>7716023
Seriously?
Algebra I.
analysis

You can do it with a u-substitution and an integral by parts
