Question:

let matrix A = [5 2 9 3] does the inverse of matrix A exists? if so, find the inverse of matrix A

Ferino H.
Answer:

a) yes the inverse of matrix A exists, because det(A) is not zero det(A) = 5*3 - 9*2 = 15 - 18 = -3 ; because det(A) is not zero, inverse of A exists b) inverse of matrix A A^-1 = (1/det(A)) * [3 -2 -9 5] A^-1 = [-1 2/3 3 -5/3]
