eigenvectors of the given matrix. 16) A= ( 1st row 5 −1 2nd row 3
1) 23) A= (1st row 3 2 2, 2nd row 1 4 1 , 3rd row -2 -4 -1)
Find the characteristic equation and the eigenvalues (and
corresponding eigenvectors) of the matrix. 2 −2 5 0 3 −2 0 −1 2 (a)

Find all distinct (real or complex) eigenvalues of A.
Then find the basic eigenvectors of A corresponding to
each eigenvalue.
For each eigenvalue, specify the number of basic eigenvectors
corresponding to that eigenvalue, then enter the eigenvalue
followed by the basic eigenvectors corresponding to that
eigenvalue.

Let A be an n × n matrix which is not 0 but A2 = 0.
Let I be the identity matrix.
a)Show that A is not diagonalizable.
b)Show that A is not invertible.
c)Show that I-A is invertible and find its inverse.
Verify that the three eigenvectors found for the two eigenvalues
of the matrix in that example are linearly independent and find the
components of the vector i = ( 1 , 0 , 0 ) in the
basis consisting of them. Using
\begin{vmatrix}1 & 0 & 0 \\ -4 & 7 & 2 \\ 10
& -15 & -4\end{vmatrix}
