Web1 dec. 2024 · Finding the eigenvectors now requires us to find a non-trivial solution for this equation. If v were zero, the equation would resolve to zero, but we wouldn’t be able to obtain λ. This is a trivial solution that we are not interested in. Instead, we need to find the solution for which the term in brackets resolves to zero. WebYou can use WolframAlpha to check your result. I wanted to mention, that it is often useful to apply what you know about eigenvalues; you can use λ 1 + λ 2 = 7, λ 1 λ 2 = − 8, λ 1 2 − 7 λ 1 + 8 = 0 when trying to solve the system. For example:
