WebIn this video I show how to solves symbolically and numerically using sympy and scipy. In particular, for a given integral, I give a sequence of steps. Firstly, determine if the integral has an analytic solution using sympy (it often does). If it doesn't, then resort to solving definite versions of the integral using scipys "quad" funcitonality.
