Review Presentation: Cross Product

Cross Products involve matrices with vectors. To find the cross product you must create a matrix using I, j, and k. You will be given two vectors: u and v, and you must find the cross product by using matrices and determinants, which will form an equation.

u: <2,1,5>

V: <-3,4,2>

these are your vectors and now you must place them into a matrix.

u x v: 2i -15j + 8k + 3k -20i -4j

u x v: -18i -20j + 11k

u x v: <-18, -20, 11>
