How to solve eigenvector problems
WebWe can easily solve the original equation Ax = λx for eigenvectors using the eigenvalue. Step 1. Find eigenvalues λ of A Step 2. For each λ, form homogeneous system of linear equations (A − Iλ)x = 0. Step 3. Solve the above equations to get eigenvectors for λ Example Find eigenvectors of A = (1 3 2 0). Step 1. Find Eigenvalues Webv 1 = ( 1 5 ( 1 − 6), 1) Since we have conjugate eigenvalues, we can write the eigenvector for the second eigenvalue as: v 2 = ( 1 5 ( 1 + 6), 1) You can now write: x ( t) = c 1 e λ 1 t v 1 + c 2 e λ 2 t v 2. Use the IC to find the constants. Your final solution should be: Share. Cite.
