Get inverse of matrix

WebFor a 2x2 matrix, the inverse is: ( a b c d) − 1 = 1 a d − b c ( d − b − c a) , where a d − b c ≠ 0. just swap the 'a' and 'd', negate the 'b' and 'c', then divide all by the determinant a d − b c. That's really the most straightforward 'trick', just memorize that pattern. For 3x3, it's lot more complicated but there is a pattern. WebStep 1: Find the determinant of matrix C.
