Myth: Eigenvalues are only related to diagonalization.

Eigenvalues are scalar values that represent how much a linear transformation changes a vector's direction and magnitude. Imagine you're working with a matrix, which can be thought of as a grid of numbers. Eigenvalues help you understand the transformation that this matrix applies to the vectors in the grid. In simpler terms, they indicate how much a particular vector is scaled or stretched by the matrix.

Common Misconceptions about Eigenvalues

Eigenvalues are closely tied to eigen vectors, which are vectors that remain unchanged under a linear transformation. Eigen vectors and eigenvalues are related in that vectors with large eigenvalues are more sensitive to the transformation, while those with small eigenvalues are less affected.
