4_4 (6 pts) Perform steps in a script HW4_4.m. The velocity (V) of air flowing past a flat surface is measured at several distances (x) away from the surface. Newton's viscosity law describes the shear stress (T) at the surface (x = 0): dv T= U dx Assume a dynamic viscosity of u = 1.8 x 10-5 N x (m) v (m/s) 0 0 0.002 0.287 0.006 0.999 0.012 2.215 0.018 3.448 0.024 4.699 Use three methods to evaluate the derivative at x = 0 and calculate t. Output your value of t for each method, and include a recommendation as to which you think will work best
