python 反余切

要画出Python中的反余切函数曲线，你可以使用numpy库中的arctan函数。下面是一段代码示例：

import numpy as np
import matplotlib.pyplot as plt

x = np.linspace(-10, 10, 1000)
y = np.arctan(x)

plt.plot(x, y)
plt.xlabel("x")
plt.ylabel("arctan(x)")
plt.title("反余切函数曲线")
plt.show()

以上代码将在一个坐标系中绘制出反余切函数曲线，横轴为x，纵轴为arctan(x)。你可以根据需要调整x的范围和曲线的样式。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
