Homework Statement
[tex]
\int_0^1 \frac{x^4(1-x)^4}{1+x^2}\ dx
[/tex]
The Attempt at a Solution
A gonio substitution gets nasty really fast moreover the differentiation under the integral sign trick doesn't seem to give more insight (at least that's what I think). Integration by parts gets a ln(.) times something nasty. The boundaries suggest a series expansion or a smart substitution...
Can someone give me a hint?
