[Numpy] 삼각함수 (sin, cos, tan)

1. sin (사인)

import numpy as np
import matplotlib.pylab as plt

x = np.linspace(-5, 5, 100)
sin = np.sin(x)

plt.plot(x, sin)
plt.title('sin(x)')
plt.show()

 

 

 

2. cos (코사인)

x = np.linspace(-5, 5, 100)
cos = np.cos(x)

plt.plot(x, cos)
plt.title('cos(x)')
plt.show()

 

 

 

3. tan (탄젠트)

x = np.linspace(-3, 3, 100)
tan = np.tan(x)

plt.plot(x, tan)
plt.ylim([-10, 10])
plt.title('tan(x)')
plt.show()
