Hi all.

Can someone help me on how to analytically evaluate the following integral:

integral of f(x) with respect to x, between limits 1 and 0 where

f(x)= x^4/(1+x^2)

I have thought about an x=tan u substitution but then i am left with a (tan u)^4 integral, and i dont know how to do that. Anyway, I don’t think it is the optimum method.

TIA
