pythonのmatplotlibでsinとcosグラフを作成 - Qiita

import matplotlib.pyplot as plt import numpy as np x = np.linspace(-2*np.pi, 2*np.pi) y1 = np.sin(x) y2 = np.cos(x) plt.plot(x, y1, color='b', ls='-', label='y=sin(x)') plt.plot(x, y2, color='r', ls='-', label='y=cos(x)') plt.xlim(-2*np.pi, 2*np.pi) plt.ylim(-1.5, 1.5) plt.xticks([-2*np.pi, -(3/2)*np.pi, -np.pi, -(1/2)*np.pi, 0, (1/2)*np.pi, np.pi, (3/2)*np.pi, 2*np.pi]) plt.legend() plt.grid() pl
