Steps(For reference): 1. Find determinant of matrix A -> detA 2. Find the matrix of co-factors (tip: the first row was partiality fond when getting the detA) 3. Set the right sings of the matrix of cofactors. Alternatating | + - + | | - + - | | + - + | 4. Transpose the matrix to find the adjoint matrix Aadj 5. Ainverse = 1/det * Aadj

I really appreciate this. Very methodical and clear. Yesterday I looked into matrices and made the formula for a 3x3 one. It was easy, although very tedious, and at the end I got stuff like this which is very confusing to apply. Let's say matrix |a b c| |d e f| |g h i| And the inverse would have in the place of a this: (ei-fh)/(aei-afh+bfg-bdi+cdf-ceg). Very sluggish and confusing. The whole thing is |(ei-fh) (ch-bi) (bf-ce)| |(fg-di) (ai-cg) (cd-af)| |(dh-eg) (bg-ah) (ae-bd)| With that long determinant as a fraction.

i think using the identity matrix is easier [ A | I ] where once you row reduce the matrix A to its identity matrix with respect to the identity matrix, the identy matrix becomes the inverse of matrix A. A~I, I~A^-1

Very well done thanks alot this is going to be very helpful. But I was wondering can I also use this for bigger or smaller matrix? So for 4x4 I could do + - + - for the first colome to get the det A and then do: + - + - - + - + + - + - - + - + to get the Adj * A and then divide Adj*A by the det A like shown in the video or does it just work for 3x3 matrix? Thx!
