This post is about relating dot products and cross products in the mathematical field of linear algebra. We also look at orthogonal (perpendicular) vectors being related to dot products and to cross products. Prerequisites It is assumed that the reader is familiar with the linear algebra concepts of dot products, orthogonal vectors and cross products.… Read more »
