If you want to compute a numerical answer using SymPy, use evalf() on the integral. But as others have pointed out if you are just doing a purely numerical integration you can also use the Julia functions to do that. SymPy will only be useful if you are interested in a symbolic answer, and in this case, a closed-form answer might not even exist.
