Math Problem Statement
Q.3 For the below matrices i) Find the eigen values and the eigen vectors. ii) Verify Cayley-Hamilton Theorem. iii)Check if they are diagonalisable, if yes find the diagonal and transforming matrix. A= [■(9&-1&9@-1&-1&3@-7&1&-7)]
Solution
Matrix Given:
Let's address each part of the question:
Part i) Find the Eigenvalues and Eigenvectors
To find the eigenvalues of matrix , we solve the characteristic equation:
Where is the eigenvalue, is the identity matrix, and represents the determinant.
Part ii) Verify Cayley-Hamilton Theorem
The Cayley-Hamilton theorem states that every square matrix satisfies its own characteristic equation. This means that if the characteristic equation of matrix is:
Then, the matrix satisfies:
Part iii) Check if the Matrix is Diagonalizable
A matrix is diagonalizable if there are linearly independent eigenvectors for an matrix. If is diagonalizable, we can write:
Where is the diagonal matrix of eigenvalues, and is the matrix whose columns are the corresponding eigenvectors of .
