In Matlab:

Calculate the Euler's Method approximate solution on [0,4] for the differential equation y=siny and initial condition (a) y0=0 (b) y0=100, using step sizes h=0.12k for 0k5. Plot the k=0 and k=5 approximate solutions along with the exact solution (see Exercise 15), and make a log-log plot of the error at t=4 as a function of h
