WebSep 17, 2024 · Example 5.5.2: A 3 × 3 matrix Find the eigenvalues and eigenvectors, real and complex, of the matrix A = (4 / 5 − 3 / 5 0 3 / 5 4 / 5 0 1 2 2). Solution We compute the characteristic polynomial by expanding cofactors along the third row: f(λ) = det (4 / 5 − λ − 3 / 5 0 3 / 5 4 − 5 − λ 0 1 2 2 − λ) = (2 − λ)(λ2 − 8 5λ + 1). WebAll steps. Final answer. Step 1/3. We know that, The diagonal elements are the eigenvalues of a lower triangular matrix. so here given that, 7 and -3 are the eigenvalues of the …
Analytical expression for the eigenvectors of a 3x3 real, symmetric matrix?
WebFeb 24, 2024 · How do I find eigenvalues of a 3x3 matrix? To find the eigenvalues λ₁, λ₂, λ₃ of a 3x3 matrix, A, you need to: Subtract λ (as a variable) from the main diagonal of A to get A - λI. Write the determinant of the matrix, which is A - λI. Solve the cubic equation, which is det (A - λI) = 0, for λ. WebApr 9, 2024 · Expert Answer.
