Web1. The determinant of a matrix is a special value that is calculated from a square matrix. It can help you determine whether a matrix has an inverse, find the area of a triangle, and let you know if the system of equations has a unique solution. Determinants are also used in calculus and linear algebra. WebAnswer (1 of 5): The determinant of a matrix is the total scaling factor, the quantity that has the property \det(AB) = \det(A)\det(B) \Rightarrow \det(A^n) = \det(A)^n A matrix is only invertible if the determinant is nonzero. Suppose A^{-1} exists then A^{-1} A = A A^{-1} = I … during my master\u0027s program

The area of the parallelogram spanned by a and b is the magnitude of a × b. We can write the cross product of a = a 1 i + a 2 j + a 3 k and b = b 1 i + b 2 j + b 3 k as the determinant. a × b = i j k a 1 a 2 a 3 b 1 b 2 b 3 . Now, imagine that a and b lie in the plane so that a 3 = b 3 = 0. WebDeterminants can be interpreted geometrically as areas and volumes.
