WebJul 1, 2024 · For each λ, find the basic eigenvectors X ≠ 0 by finding the basic solutions to (λI − A)X = 0. To verify your work, make sure that AX = λX for each λ and associated eigenvector X. We will explore these steps further in the following example. Example 8.1.2: Find the Eigenvalues and Eigenvectors Let A = [− 5 2 − 7 4]. WebJun 10, 2024 · Determinant. The signed area of the parallelogram stretched by the eigenvectors of matrix A equals to the determinant. Note that this area can be negative when a eigenvector is negative; Note the area is 0 when the matrix A is rank deficient (it does not stretch into a full volume in the n-dimensional space)
WebSolve the system of equations using Cramer’s Rule: { 3 x + y − 6 z = −3 2 x + 6 y + 3 z = 0 3 x + 2 y − 3 z = −6. Cramer’s rule does not work when the value of the D determinant is 0, as this would mean we would be dividing by 0. But when D = 0, the system is either inconsistent or dependent.
