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. WebThe matrix determinant is a number derived from the values in array. For a three-row, three-column array, A1:C3, the determinant is defined as: MDETERM (A1:C3) equals A1* (B2*C3-B3*C2) + A2* (B3*C1-B1*C3) + A3* (B1*C2-B2*C1) Matrix determinants are generally used for solving systems of mathematical equations that involve several variables.
