Use the centered finite difference method to show a graphical representation of how decreasing the step size, h, of the following system can show the approximation approaching the exact function curve. The position and velocity function that represents this system are given by f(t) = 0.5et3i+ 0.5e-t3i , respectively. Begin with h = 1 and Ah = 0.3 until h = 0.1. The operation of this system lasts 10 seconds. Hz(t) m
