find inverse of matrix A, verify that AA to power -1=1

the inverse of a matrix can be created by a gauss-jordan appoach. consider row operations than turn the first matrix into the second. the inverse is the second part of the second matrix.

Code: Select all

first matrix second matrix a b c 1 0 0 = 1 0 0 r s t d e f 0 1 0 = 0 1 0 u v w g h i 0 0 1 = 0 0 1 x y z
Find the inverse of matrix A, listed below, using this technique.

Code: Select all

2 3 -1 A= 4 2 1 1 3 5
verify that you have the inverse by using the property that AA to the power of -1=1
