Graph trigonometric functions with numpy and matplotlib
Import modules that handle formulas easily and modules that can be converted into graphs. </ strong>
import matplotlib.pyplot as plt
Sine, cosine, tangent display </ strong>
x = plt.linspace(-np.pi,np.pi) #Specifying the horizontal display of the graph
plt.plot(x, np.cos(x), color='r', ls='-', label='cos') #Display of cosine
plt.plot(x, np.sin(x), color='b', ls='-', label='sin') #Display of sign
plt.plot(x, np.tan(x), color='c', marker='s', ls='None', label='tan') #Display of tangent
Graph vertical / horizontal display specification </ strong>
plt.xlim(-np.pi, np.pi)
plt.ylim(-1.5, 1.5)```
