Python| Sympy is_tangent() 方法

在 Sympy 中，函数is_tangent()用于检查给定线是否与给定圆相切。

Syntax:  Circle().is_tangent(line)

Return: True:if line is tangent to circle, otherwise 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
