Hi all,

I am struggling to find a way to substitution for integral of x^2/sqr(1-x)dx.

If it was x^3 in the square root I would know how to do it, but because numerator is lower power than denominator

Thanks

You are right. My teacher did not teach us that before. She always said find the outside and inside function and make substitutions, like $\displaystyle \sqrt{x-1}\$ would be $\displaystyle f(x)=\sqrt{x}\$ and $\displaystyle g(x)=x-1$

thanks for the tip. - May 18th 2008, 08:33 PMMathstud28
