as we do, to refer to the Z component of the actual cross product of your 2D vectors extended to 3D. In some code bases they also call this "the determinant”, which is an operation you can do on a matrix
The above definition also extends to vectors. Let’s say that you have two vectors v and w; Each vector is multiplied by a scalar a and b, giving the expression: av + bw. The expression av + bw is called a linear combination of v and w. Using a little linear algebra, you can sh...
