Python| Sympy Line.is_perpendicular 方法

在 Sympy 中，函数is_perpendicular()用于检查两个线性实体是否垂直。

Syntax: Line.is_perpendicular(l2)

Parameters:
 l1: LinearEntity
 l2: LinearEntity

Returns:
 True: if l1 and l2 are perpendicular,
 False: otherwise.

示例 #1：

# import sympy and Point, Line
from sympy import Point, Line
   
p1, p2, p3 = Point(0, 0), Point(1, 1), Point(-1, 1)
  
l1, l2 = Line(p1, p2), Line(p1, p3)
  
# using is_perpendicular() method
isPerpendicular = l1.is_perpendicular(l2)
  
print(isPerpendicular)

输出：

True

示例 #2：

# import sympy and Point, Line
from sympy import Point, Line
   
p1, p2, p3 = Point(0, 0), Point(1, 1), Point(5, 3)
  
l1, l2 = Line(p1, p2), Line(p1, p3)
  
# using is_perpendicular() method
isPerpendicular = l1.is_perpendicular(l2)
  
print(isPerpendicular)

输出：

False
