    Question Can you help me with this integral?

    I'm having trouble solving this integral. It would be great if anybody could help me out, I admit to being a pretty poor mathematician and Maple couldn't solve it for me...

    \int_{0}^{Rcluster}(1+(r/R_c)^2)^B *r^2 dr

    Rcluster, B and Rc are known variables.

    I have a mind block at the finish, but substitution clears the integrand up:

    u=1+\frac{r^2}{R_c^2}
    du=\frac{2rdr}{R_c^2}

    Integral then becomes: \int 0.5u^B R_c^3 \sqrt{1-u}du
