Write a python program that plot the fundamental hormonic and the 2nd , 3rd, 4th, 5th , 6th , 7th , 8th and 9th harmonic of the problem 7. Hint: Start with the program from #7 and modify it by adding a loop to produce the harmonics.

Your final graph should be look like the figure below. Figure size = (16,8):

#program from problem 7

import matplotlib.pyplot as plt import numpy as np import pandas as pd f = 60 T = 1 / f step = T / 100 t = np.arange(0, T, step) y = np.sin(2*np.pi*f*t) plt.plot(t*1000, y) plt.title('Fundamental Harmonic f=60Hz') plt.xlabel('Time (ms)') plt.ylabel('Magnitude') plt.legend(['f=60Hz']) plt.show()
