Python | Sympy Ellipse.rotate() method
• Last Updated : 30 Jan, 2020
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)`
