Difficult integral

[gabi27]

Hi there, can anyone help me solve this integral?

x/{(1-x^4)^(1/2)}

Have been trying for last 3 days, but no joy:roll: At least some kind of clue would be very appreciated

substitute:

x² = sin(u)

Since you have been trying for 3 days - surely you have some work to share!!!

Thanks so much, I solved it now, I was nearly there, just kept trying x = sin(u), which wasn't really getting me anywhere
