Python | Sympy Ellipse.rotate() method

In Sympy, the function rotate() is used to rotate the ellipse counterclockwise about the given point by the given angle.

Syntax: Ellipse.rotate(angle=0, pt=None)

Parameters:
angle: in radian
pt: point about which ellipse is rotated in counterclockwise.

Returns: rotated ellipse

Example #1:

# import sympy and pi, Ellipse
from sympy import Ellipse, pi

# using Ellipse() method
e1 = Ellipse((1, 0), 2, 1)

# using rotate() method
e1.rotate(pi / 2)

print(e1)

Output:

Ellipse(Point2D(0, 1), 1, 2)

Example #2:

# import sympy and pi, Ellipse
from sympy import Ellipse, pi

# using Ellipse() method
e2 = Ellipse((1, 0), 2, 1)

# using rotate() with given point method
e2.rotate(pi / 2, (1, 2))

print(e2)

Output:

Ellipse(Point2D(3, 2), 1, 2)
