Question

what is the integral of xtanx?
is it even possible?

Answer 1

Yes it is of course. It is a basic integration by parts. :)

Answer 2

but it just becomes more complex

Answer 3

first of all, do you know integration by parts?

Answer 4

I do, but when I plug back in v and u and du, it just becomes longer and harder to solve. I can't find the integral of ln(sec(x))

Answer 5

try to let u = tanx

Answer 6

I'm still not getting it. how would I integrate x^2 /2 * tanx??

Answer 7

dont you know that \[\int\limits uv = uv - \int\limits vdu\]
