MATLAB CODE HELP

3. Derivatives d2 dt2 Assume y(t) = A cos(w t) + B sin(w t). Use Matlab and the diff function to find + y. Simplify the expression using the simplify function. Use the collect function twice to get a result with the cos (wt) and sin (wt) terms grouped together. Experiment with pretty and latex (and an online LaTeX renderer) to see the output in neater forms
