Mathematics - Vectors and Matrices
is
- Option : C
- Explanation : For the matrix
cofactors are
a11= 1, a21 = -5, a12 = -2, a22 = -3
Therefore matrix by cofactors
Adjoint A
I A I = -3(1) - 5(2)
= -3 - 10
= -13
62. If A and B are square matrices of size n × n ,
then which of the following statement is not true?
63. If A be an invertible matrix and inverse of 7A is
then matrix A is
- Option : A
- Explanation : Inverse of 7A=
= 7 - 8 = -1
Therefore matrices of co factor
and its transpose,
then state transition matrix eAt is
one of the eigen values is equal to -2.
which of the following is an eigen vector?
