Eigenvalues Analysis
Definition: Eigenvalues are scalar values associated with a square matrix that satisfy the equation A × v = λ × v, where A is the matrix, λ is the eigenvalue, and v is the eigenvector. Eigenvalues represent the scaling factors of the eigenvectors during linear transformations.
Key Concept: If λ is an eigenvalue of a matrix A, then λⁿ is an eigenvalue of the matrix Aⁿ, where n is a positive integer. This property arises from the fact that eigenvalues maintain their relationship with the matrix's powers during successive matrix multiplications.
Solution:
Given the eigenvalues of matrix A as 1, 3, and 5:
- For A³, the eigenvalues are calculated as λ³, where λ are the eigenvalues of A.
- Thus, the eigenvalues of A³ are:
- (1)³ = 1
- (3)³ = 27
- (5)³ = 125
Therefore, the eigenvalues of A³ are 1, 27, and 125.
