3. A simple harmonic is a function of the form: y = a cos (w t) + b sin(w t). It can be written as y= A cos(wt + p) where A is amplitude and o is phase. Find the amplitude and phase of y= 2 cos(3 t) - 5 sin(3 t). Plot y 2 cos (3)-5 sin(3 t) on [0, 2 x] as a solid line and plot on the same figure the equivalent form y= A cos(wt+o) as red circles; again, do not forget labels, title, and legend.
