You are given an analytic solution for three flows as follows: Flow 1: y = sin (x) Flow 2: y = x Flow 3: y = x² You aim to understand how accurately you can approximate the derivative using finite differences. Evaluate the numerical error compared to the analytic solution (by differentiating the above eqn) as a function of mesh size Ax. (a) For the first derivative using a 1st and 2nd order Finite difference (b) For the second derivative using a 1st and 2nd order Finite difference (c) Which mesh size yields roughly 5% accuracy?
