Printable 3x3 Eigenvalues Worksheet
This worksheet is for students practicing eigenvalues of 3x3 matrices. It includes Name and Date fields, a directions line that says to find the eigenvalues with a hint that the matrices are triangular, and a set of problem-and-answer columns. The problems use 3x3 triangular matrices, with space laid out in two side-by-side columns. An answer key follows on a separate section with each matrix and its eigenvalues listed.
