如何在Python中将两个不同的函数绘制在同一图形中

import matplotlib.pyplot as plt
import numpy as np

def function1(x):
    # 第一个函数的定义
    y1 = np.sin(x)
    return y1

def function2(x):
    # 第二个函数的定义
    y2 = np.cos(x)
    return y2

x = np.linspace(0, 2*np.pi, 100)  # 生成0到2π之间的100个数据点

y1 = function1(x)
y2 = function2(x)

plt.plot(x, y1, label='Function 1')
plt.plot(x, y2, label='Function 2')

plt.legend()  # 添加图例
plt.xlabel('x')  # x轴标签
plt.ylabel('y')  # y轴标签
plt.title('Two Functions')  # 图形标题

plt.show()

import matplotlib.pyplot as plt
import numpy as np

def function1(x):
    y1 = np.sin(x)
    return y1

def function2(x):
    y2 = np.cos(x)
    return y2

x = np.linspace(0, 2*np.pi, 100)
y1 = function1(x)
y2 = function2(x)

plt.plot(x, y1, label='Function 1')
plt.plot(x, y2, label='Function 2')

plt.legend()
plt.xlabel('x')
plt.ylabel('y')
plt.title('Two Functions')

plt.show()
