WebIn mathematics, the determinant is a scalar value that is a function of the entries of a square matrix.It characterizes some properties of the matrix and the linear map represented by the matrix. In particular, the determinant is nonzero if and only if the matrix is invertible and the linear map represented by the matrix is an isomorphism.The … 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.
