Compute . Solution: We next define the cross product of two vectors. Definition: If . a = i + j + k. and . b = i + j + k . be vectors in 3D space. The cross product is the vector. i + j + k. To calculate the cross product more easily without having to remember the formula, we using the following “determinant” form.

Note: The determinant can be determined (expanded) along any row or column. Sample Problem 8: Find the minors M1 3, M2 3, M3 3, the cofactors C1 3, C2 3, C3 3, and the determinant of the matrix . Properties of the Determinant: If A is a p(p matrix, then: (1) det (A) = the product of the diagonal entries if A is a triangular matrix
