what is the matlab code to complete the following. using matlab

I 5. By w, I denote the angular speed where w = = {1,1,2}. On three subplots, plot the unit-sine function sin(wt). u(t). 6. By T, I denote the time constant where t = {1,3,9}; and by w, I denote the angular speed where w = {1,1,2). On a 3 by 3 grid of nine subplots, plot the unit-exponentially-decaying sine function e + .sin(wt) .u(t)
