Formula for finding the inverse of a 2x2 matrix. 2. Formula for finding the inverse of a 3x3 matrix requires to find its determinant, cofactor and finally the adjoint matrix and the apply one of the following formulas: how to find the reflection of a rational function The cofactor matrix replaces each element in the original matrix with its cofactor (plus or minus its minor, which is the determinant of the original matrix without that row and column. The plus or minus rule is the same for determinant expansion -- if the sum of the row and column is even, it's positive, if negative, it's odd).
