Find the determinant of a 3x3 matrix

WebDeterminants. Determinants are the scalar quantities obtained by the sum of products of the elements of a square matrix and their cofactors according to a prescribed rule. They help to find the adjoint, inverse of a matrix. Further to solve the linear equations through the matrix inversion method we need to apply this concept. WebTo find the determinant of a 3x3 matrix, use the formula A = a(ei - fh) - b(di - fg) + c(dh - eg), where A is the matrix: [a b c] [d e f] [g h i] How do I find the determinant of a large …
