This module implements 2d rotation matrix functionalities.
Given an angle of rotation \(\theta\) a 2d rotation matrix can be expressed as
\[
\mathbf{R} =
\begin{bmatrix}
\cos(\theta) & -\sin(\theta) \\
\sin(\theta) & \cos(\theta)
\end{bmatrix}.
\]
More details rotation matrices can be found on this page.
