Parameters:o  an Ellipse, LinearEntity or Polygon

返回: True if o is tangent to the ellipse, False otherwise.

Raises: NotImplementedError When the wrong type of argument is supplied.

范例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

范例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:
