原文:https://www.geesforgeks.org/python-sympy-ellipse-is_tangent-method/
In Sympy, the function Ellipse.is_tangent() is used to check whether an Ellipse, LinearEntity or Polygon is tangent to the given Ellipse or not.
Syntax: is_tangent(o)
Parameters: o an Ellipse, LinearEntity or Polygon
Returns: True if o is tangent to the ellipse, False otherwise.
Raises: NotImplementedError When the wrong type of argument is supplied.
示例#1:
# import sympy and Point, Ellipse, Line
from sympy import Point, Ellipse, Line
p0, p1, p2 = Point(0, 0), Point(3, 0), Point(3, 3)
# using Line and Ellipse method
e1 = Ellipse(p0, 3, 2)
l1 = Line(p1, p2)
# using is_tangent method
e1.is_tangent(l1)
输出:
True
示例#2:
# import sympy and Point, Ellipse, Line
from sympy import Point, Ellipse, Line
p0, p1, p2 = Point(0, 0), Point(4, 0), Point(4, 2)
# using Line and Ellipse method
e1 = Ellipse(p0, 3, 2)
l1 = Line(p1, p2)
# using is_tangent method
e1.is_tangent(l1)
输出:
False
