What does it mean to "solve" that? Are you trying to find the bounds such that the result has a particular value?

See int() for symbolic calculation and integral() for numeric calculation.

This is a direct trigonometric substitution problem. I'm trying to get the following result in MatLab (see attached).

Answer 1

In terms of real numbers the integral is only defined for -1<=x<=1. By making the substitution x^2 = sin(theta) where -pi/2<=theta<=pi/2 it is easy enough to find the integral as theta/4 + sin(2*theta)/8.
