👉 In mathematics, a reline is a mathematical operation that involves shifting or rotating a vector in space. It is often used in geometry and linear algebra to represent transformations on a line, such as rotations and translations.
For example:
A vector (x, y) can be represented by the matrix:
\[
\begin{pmatrix}
x \\
y
\end{pmatrix}
\]
The operation of shifting this vector to the right by
