Let 

Find y(t) analytically and determine a value of T_s for which

(consider as possible values T_s = 0:01 and T_s = 0:1). Use the MATLAB function diff or create your own to compute the finite difference. Plot the finite difference in the range [0; 1] and compare it with the actual derivative y(t) in that range. Explain your results for the given values of T_s.
