Python绘制sin(x)和cos(x)函数图像

import matplotlib.pyplot as plt import numpy as np

fig, (ax1, ax2) = plt.subplots(1, 2, figsize=(10,5)) x = np.linspace(-np.pi, np.pi, 100) y1 = np.sin(x) y2 = np.cos(x)

ax1.plot(x, y1, linewidth=2.5) ax1.set_title('sin(x)') ax1.set_xlim([-np.pi, np.pi]) ax1.set_ylim([-1, 1])

ax2.plot(x, y2, linewidth=2.5) ax2.set_title('cos(x)') ax2.set_xlim([-np.pi, np.pi]) ax2.set_ylim([-1, 1])

plt.show()
