Since the given matrix is triangular, its eigenvalues are its diagonal elements.
00:17
Therefore, eigenvalues are 1 ,1 ,2.
00:22
This matrix is diagonalizable if and only if arithmetic multiplicity i .e.
00:37
Am of eigenvalues is equal to geometric multiplicity i .e.
00:49
Gm am of eigenvalue 1 is equal to gm of eigenvalue 2.
01:06
Am of eigenvalue 2 is equal to number of times eigenvalue 2 occurs i .e.
01:18
1.
01:19
And since am of an eigenvalue is always greater than or equal to gm, so gm of eigenvalue 2 is equal to 1.
01:38
Therefore, am of eigenvalue 2 is equal to gm of eigenvalue 2.
01:49
Whatever may a, b, c be.
01:55
Am of eigenvalue 1 is equal to number of times eigenvalue 1 occurs i .e...
