WebAug 1, 2024 · Solution 3. Note that the matrix kA has elements [kA]ij = kAij, where Aij are the elements of A. If we were to calculate the determinant expression formula, each term has the factor k appearing n times, where n is the dimension of the matrix. You can factor these out from the entire expression, and you're left with something proportional to det A. WebMay 9, 2024 · Algebraically, the determinant tells you whether the transformation is invertible (det(A) ≠ 0) or is singular (det(A) = 0). When A is a constant matrix, det(A) is a number. But if some cells in the matrix depend on a parameter, then the determinant is a function of that parameter.
