i saw this integral in a previous post and i'm curious on how to do it. i tried a wierstrauss substitution but that seems to make the problem extremely complicated. i also tried rewriting as but i'm not sure on what to do next.
what would be the best way to tackle this integral?
Multiply numerator and denominator by and then substitute and you should be able to work your way from there.
and then use partial fractions (just an alternate way of solving).
and then use partial fractions again.
[Next time, make all of your ideas into one single post. -K.]
