You could of separated it from the beginning first: \[\int\limits \frac{ \sec^2(x) }{ \tan^2(x) }dx - \int\limits \frac{ 1 }{ \tan^2(x) }dx \] use u-substitution: u = tan(x) du = sec^2(x) \[\int\limits \frac{ 1 }{ u^2 }du - \int\limits \frac{ 1 }{ \tan^2(x) }dx\] and you know: \[\frac{ 1 }{ \tan^2(x) }= \frac{ 1 }{ \frac{ \sin^2(x) }{ \cos^2(x) } } = \frac{ \cos^2(x) }{ \sin^2(x) }= \cot^2(x)\] proceed: \[\int\limits \cot^2(x)dx = -x-\cot(x)+C\] PUT EVERYTHING TOGETHER: \[-\frac{ 1 }{ \tan(x) }-(-x-\cot(x))+C\]

You got the questions wrong @abb0t . Its tan/sec not the other way around
anonymous
  • anonymous
you did the question wrong
abb0t
  • abb0t
omg. Lol. fudge.
anonymous

The int of sec^2 is tan. You dont need any other steps to compute that.
anonymous
  • anonymous
the sec^2x cancel out leaving 2/sec^2x which is 2ln(tanx) right
anonymous

you cant just throw the 1 away. Its 1, not 0

am i looking @ the wrong question?! LOL

lol. whoa watch out, we got a bada_ _!! JK he's human and still susceptible to mistakes.

Well im 4 months away too, in electrical engineering to be precise.
anonymous
  • anonymous
me too woot
anonymous
  • anonymous
im also ece

  • anonymous
but im second year 19 so if i try hard enough i may get done by 21

i'm abt 2 graduate 8th grade.
anonymous
  • anonymous
avoided math as much as i could :P
anonymous
  • anonymous
hahahhaa
anonymous
  • anonymous
yea right abo0t
anonymous
  • anonymous
You prolly still have to take diffe eq, multi variate and statistics then. Good luck lol
abb0t
  • abb0t
Don't forget Linear Algebra.
anonymous
  • anonymous
So smart for someone who is in 8th grade
anonymous
  • anonymous
yea i do and i hate math so not the best major for me XD
anonymous
  • anonymous
i found abb0t secret http://www.youtube.com/watch?v=lXp7Ta1UmQA
anonymous
  • anonymous
hest that dude right there
abb0t
  • abb0t
omg. lol. i was guessing. geezbus. Lol
anonymous

Dont give up though, the degree is hot cake once you graduate. I promise
anonymous
  • anonymous
i know thats why im keeping at it
anonymous
  • anonymous
and i know some people that got direct to intel from here for 100k + so im gonna work my retriceoff

butt off*
anonymous
  • anonymous
and hes 21 as well so should be a good life from then on :P
anonymous

And that youtube guy is on a whole different level. As long as he can spit off derivatives and int from his head when he turns 18, otherwise he will be that one yotube guy
anonymous
  • anonymous
that was just a quick google search btw so im sure there are more genious of abb0t level ;)
