Let y(t) = dx(t)/dt, where x(t) = 4cos(2t), < t < . Find y(t) analytically
Question:
Let y(t) = dx(t)/dt, where x(t) = 4cos(2πt), − ∞ < t < ∞. Find y(t) analytically and determine a value of Ts for which ∆[x(nTs)]/Ts = y(nTs)(consider as possible values Ts = 0.01 and Ts = 0.1). Use the MATLAB function dif for 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 Ts.
