Python| Sympy Line.perpendicular_line 方法

在 Sympy 中，函数垂直线（）用于创建一条垂直于给定线性实体的新线，该线通过给定点 p。

Syntax: Line.perpendicular_line(p)

Parameters:
p: Point

Returns:line 

示例 #1：

Python3

# import sympy and Point, Line
from sympy import Point, Line
  
p1, p2, p3 = Point(0, 0), Point(2, 3), Point(-2, 2)
  
l1 = Line(p1, p2)
  
# using perpendicular_line() method
l2 = l1.perpendicular_line(p3)
  
# checking l2 is perpendicular to l1 using is_perpendicular() method
isPerpendicular = l1.is_perpendicular(l2)
  
print(isPerpendicular)

输出：

True

示例 #2：

Python3

# import sympy and Point3D, Line3D
from sympy import Point3D, Line3D
  
p1, p2, p3 = Point3D(0, 0, 0), Point3D(2, 3, 4), Point3D(-2, 2, 0)
  
l1 = Line3D(p1, p2)
  
# using perpendicular_line() method
l2 = l1.perpendicular_line(p3)
  
# checking l2 is perpendicular to l1 using is_perpendicular() method
isPerpendicular = l2 = l1.is_perpendicular(p3)
  
print(isPerpendicular)

输出：

True
