Question

Determining Eigenvalues of a matrix :
A. Solve the characteristic equation
B. Form matrix \(A-\lambda I\)
C. Compute determinant
D. Identify eigenvalues Choose the correct answer from the options given below :

• A. A, B, C, D
• B. B, C, A, D
• C. C, A, D, B
• D. D, A, C, B

Hint:

To find eigenvalues of a matrix: \[ A-\lambda I \rightarrow \det(A-\lambda I) \rightarrow \det(A-\lambda I)=0 \rightarrow \text{Solve for }\lambda \]

Answer 1

The Correct Option is B
