Question 1
Find the ad-joint of the following matrix
|
Solution:
|
minor of 2 |
|
|||||||||
|
= [2-(-1)] = (2+1) = 3 | ||||||||||
|
Cofactor of 2 |
= + (3) = 3 |
|
minor of 1 |
|
|||||||||
|
= [2-1] = 1 | ||||||||||
|
Cofactor of 1 |
= -(1) = -1 |
|
minor of 1 |
|
|||||||||
|
= [-1-1] = -2 | ||||||||||
|
Cofactor of 1 |
= + (-2) = -2 |
|
minor of 1 |
|
|||||||||
|
= [2-(-1)] = [2+1] = 3 = 3 | ||||||||||
|
Cofactor of 1 |
= - (3) = -3 |
|
minor of 1 |
|
|||||||||
|
= [4-1] = 3 = 3 | ||||||||||
|
Cofactor of 1 |
= + (3) = 3 |
|
minor of 1 |
|
|||||||||
|
= [-2-1] = -3 = -3 | ||||||||||
|
Cofactor of 1 |
= - (-3) = 3 |
|
minor of 1 |
|
|||||||||
|
= [1-1] = 0 | ||||||||||
|
Cofactor of 1 |
= + (0) = 0 |
|
minor of -1 |
|
|||||||||
|
= [2-1] = 1 | ||||||||||
|
Cofactor of -1 |
= - (1) = -1 |
|
minor of 2 |
|
