4. Define a Python function named plot sine to sketch the 2-D graph (plot) of the function g ( t ) = A sin ( 2 f t + P hi ) For N periods starting from t = 0 s , where A , f (in Hertz), Phi (in Degrees) and N are the arguments of the function. Hints: 1. A period can be calculated by T = f 1 in seconds. 2. Since the trigonomertic functions uses Radian as the unit of angles you may remember that 18 0 = .
