Question: Find the eigenvalues of a matrix ((-2,-4,2),(-2,1,2),(4,2,5))?
Given matrix A= [(-2,-4,2),(-2,1,2),(4,2,5)]
To get the characteristic equation of matrix A, make
A-VI=0, where I is an Identity matrix.
Det [(-2-v,-4,2),(-2,1-v,2),(4,2,5-v)]= 0
By expanding the determinant:
By applying trial and error method, we got
That means eigenvalues are 3,-5,6

1. Does every matrix have eigenvalues?
Every matrix has an eigenvalue, but it may be a complex number.
2. What does a zero eigenvalue means?
Geometrically, zero eigenvalue means no information in an axis. We all know that the determinant of a matrix is equal to the products of all eigenvalues. If one or more eigenvalues are zero then the determinant is zero and which is a singular matrix.
3. Are eigenvalues unique?
Eigenvalues are not unique.
4. What is the eigenvalue of a matrix?
Eigenvalues are the special set of scalars associated with a linear system of equations known as characteristic roots and values.
