I need help integrating this function. I've done integration by parts many times, and it seems to be an infinite loop. Please help, would be greatly appreciated! :)

Ahh ok. But when I get to

-cot^2(x) - integral(csc^2(x)cot(x) dx)

I don't know what to do. Thanks a lot - Sep 29th 2012, 05:15 AMTheEmptySetRe: Integration of 1/sin^4(x)
