WebNov 25, 2024 · You can then find the other eigenvalue(s) by subtracting the first from the trace and/or dividing the determinant by the first (assuming it is nonzero…). Note: This is true for any sized square matrix. The trace will be the sum of the eigenvalues, and the determinant will be the product. Example: Let \(A=\begin{pmatrix}-1&2\\-3&4\end{pmatrix}\). WebThe eigenvalues of a 2 × 2 matrix can be expressed in terms of the trace and determinant. λ ± = 1 2 ( tr ± tr 2 − 4 det) Is there a similar formula for higher dimensional matrices? Approach The trace and determinant of a matrix are equal to the trace and determinant of the matrix in Jordan normal form.
