尝试使用数组在python中绘制三角函数

pip install numpy matplotlib

import numpy as np
import matplotlib.pyplot as plt

# 创建一个从0到2π的等差数列，包含100个点
x = np.linspace(0, 2 * np.pi, 100)

# 计算每个点的正弦值
y = np.sin(x)

# 绘制正弦函数图像
plt.plot(x, y)

# 设置标题和坐标轴标签
plt.title('Sine Function')
plt.xlabel('x (radians)')
plt.ylabel('sin(x)')

# 显示图像
plt.show()

y = np.cos(x)

y_sin = np.sin(x)
y_cos = np.cos(x)
y_sum = y_sin + y_cos

plt.plot(x, y_sum)
plt.title('Sum of Sine and Cosine Functions')
plt.xlabel('x (radians)')
plt.ylabel('sin(x) + cos(x)')
plt.show()
