How to take inverse of 3x3 matrix
WebFor 3x3, it's lot more complicated but there is a pattern. As usual compute the determinant first (kind of a pain; but surely you already know the pattern to compute that quickly). ... Well, sorta. if it's nonsingular, the determinant is 0, and so the method will work in that it will also fail when the inverse of a matrix will fail (when it is ... WebYou can check your work by multiplying the inverse you calculated by the original matrix. If the result IS NOT an identity matrix, then your inverse is incorrect. If A is the matrix you want to find the inverse, and B is the the inverse you calculated from A, then B is the inverse of A if and only if AB = BA = I 1 comment ( 7 votes) Upvote Downvote
