1. Homework Statement

Can you give me a strategy or get me started in the right direction?

I need to evaluate:

[tex] \int_{x_1}^{x_2} (E-\alpha |x|^{\nu})^{\frac{1}{2}} \,dx [/tex]

2. Homework Equations

[tex] \nu > 0 [/tex]

x1 and x2 are known in terms of E, alpha, and nu

3. The Attempt at a Solution

okay I fixed a crucial mistake (forgetting the dx). I wonder if that will help, now that you know what variable I'm supposed to be integrating wrt.

For arbitrary [itex] \nu [/itex] it's typically an elliptic integral.
