Cross Product

|
The cross product is a product of two vectors that results in a vector perpendicular to both.
Cross product is a high school-level concept that would be first encountered in a pre-calculus course covering vectors.
Prerequisites
| Dot Product: | The dot product is particular product of two vectors which results in a scalar corresponding to the length of the projection of one vector onto the other. |
| Perpendicular: | Two lines, vectors, planes, etc. that intersect at a right angle are said to be perpendicular. |
| Vector: | (1) In vector algebra, a vector mathematical entity that has both magnitude (which can be zero) and direction. (2) In topology, a vector is an element of a vector space. |
