Python Sympy is_tangent()方法

在Sympy中，函数is_tangent()是用来检查给定的直线是否与给定的圆相切的。

语法: Circle().is_tangent(line)

返回： True:如果直线与圆相切，否则为False。

示例 #1:

# import sympy and geometry module
from sympy import * 
from sympy.geometry import * 
  
x = Point(0, 0)
  
# making line with given points
l = Line(Point(5, -5), Point(5, 5))
  
# making circle with Circle() of 
# radius 5 and using is_tangent()
isTangent = Circle(x, 5).is_tangent(l)
  
print(isTangent)

输出:

True

示例 #2:

# import sympy and geometry module
from sympy import * 
from sympy.geometry import * 
  
x = Point(0, 0)
y = Point(1, 1)
  
# making line with given points
l = Line(x, y)
  
# making circle with Circle() of radius 5 and using is_tangent()
isTangent = Circle(x, 5).is_tangent(l)
  
print(isTangent)

输出:

False
