This looks like a pretty nasty integral, what class is this for? :)

My first thought would be integration by parts, actually.

ok i wud go in this way by integration by parts take 8 out now u left with (\[8\int\limits_{x}^{1}(\ln(1+t)/(1+t^2)\] now take 1/(1+t^2) as part to integrate , and derivative ln (1+t)

You've neglected to mention the integral \[ \int_0^1 \frac{\tan^{1}(x)}{1+x} dx \] which is pretty damn complicated, I would say.

4 i (Li_2((1/2i/2) (t+1))+Li_2((1/2+i/2) (t+1))+log(t+1) (log((1/2i/2) (t+i))log(1(1/2i/2) (t+1))))+constant

jem bt what else cud b easier way other than by parts to teach a high scool student
 2 years ago

Jemurray3 Group TitleBest ResponseYou've already chosen the best response.3
you're missing my point, integration by parts still requires you to solve that integral I wrote, which is kinda rough.
