数组,并绘制出图像。
```python
import numpy as np
import matplotlib.pyplot as plt
# 设置圆心坐标
center = np.array([0, 0])
# 设置内外圆半径
r1 = 6
r2 = 3
# 生成内外圆上的点
theta1 = np.linspace(0, 2*np.pi, 100)
x1 = r1*np.cos(theta1) + center[0]
y1 = r1*np.sin(theta1) + center[1]
theta2 = np.linspace(0, 2*np.pi, 100)
x2 = r2*np.cos(theta2) + center[0]
y2 = r2*np.sin(theta2) + center[1]
# 设置两条直线的夹角
angle = np.pi/3
# 设置直线的斜率和截距
k1 = np.tan(angle/2)
b1 = 0
k2 = np.tan(-angle/2)
b2 = 0
# 生成两条直线上的点
x3 = np.linspace(-10, 10, 100)
y3 = k1*x3 + b1
x4 = np.linspace(-10, 10, 100)
y4 = k2*x4 + b2
# 将所有点保存到一个numpy数组中
points = np.vstack((np.vstack((np.vstack((np.vstack((x1, y1)), x2)), y2)), np.vstack((np.vstack((x3, y3)), np.vstack((x4, y4)))))).T
# 绘制图像
plt.figure(figsize=(8, 8))
plt.plot(x1, y1, 'r-', linewidth=2)
plt.plot(x2, y2, 'r-', linewidth=2)
plt.plot(x3, y3, 'b-', linewidth=2)
plt.plot(x4, y4, 'b-', linewidth=2)
plt.axis('equal')
plt.show()
```
绘制出的图像如下所示:
