*What are they?*

Imagine a linear transformation (represented by a matrix) acting on a vector space. Most vectors will change direction and magnitude. However, there might be special vectors that only get scaled by the transformation, without changing direction. These special vectors are called *eigenvectors*, and the scaling factor is called the *eigenvalue*.

*The Eigenvalue Equation:*

The fundamental equation defining eigenvalues and eigenvectors is:
