python 绘制三角函数图形 sin、con、arcsin、arccos

1、正弦和余弦的图形

import numpy as np
from matplotlib import pyplot as plt

%matplotlib notebook

x = np.linspace((-np.pi)*2, np.pi*2, 50, endpoint=True)
y1, y2 = np.sin(x), np.cos(x)

plt.plot(x, y1, c=\'g\', marker=\'s\', label=\'sin(x)\')
plt.plot(x, y2, c=\'r\', marker=\'o\', label=\'con(x)\')
plt.legend(loc=\'upper left\', numpoints=2,)

 

 

2、反正弦和反余弦的图形

import numpy as np
from matplotlib import pyplot as plt

%matplotlib notebook

x = np.linspace(-4, 4, 100)
y1, y2 = np.arcsin(x), np.arccos(x)

plt.plot(x, y1, c=\'b\', marker=\'s\', label=\'arcsin(x)\')
plt.plot(x, y2, c=\'r\', marker=\'o\', label=\'arccon(x)\')
plt.legend(loc=\'upper right\', numpoints=2,)
plt.ylim(-4, 4)
