Python绘制sin(x)和cos(x)函数图像

import matplotlib.pyplot as plt import numpy as np

x = np.linspace(-np.pi, np.pi, 1000)

fig, (ax1, ax2) = plt.subplots(1, 2, figsize=(10, 5))

ax1.plot(x, np.sin(x), linewidth=2.5) ax1.set_title('sin(x)')

ax2.plot(x, np.cos(x), linewidth=2.5) ax2.set_title('cos(x)')

plt.show()
