Python Sympy Line.perpendicular_line用法及代码示例


在Sympy中,该函数perpendicular_line()用于创建一条垂直于给定线性实体并穿过给定点p的新线。
Synatx: Line.perpendicular_line(p)

参数:
p: Point

返回:line 

范例1:

# 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

范例2:

# 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
