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.

Example #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)

Output:

True

Example #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)

Output:

False
