Cross product
mathematical operation on two vectors / From Wikipedia, the free encyclopedia
For other products in mathematics, see Product (mathematics).
The cross product is a mathematical operation which can be done between two three-dimensional vectors. It is often represented by the symbol .[1] After performing the cross product, a new vector is formed. The cross product of two vectors is always perpendicular (it makes a corner-shaped angle) to both of the vectors which were "crossed".[2][3] This means that cross product normally works only in three-dimensional space; that is, anywhere where you can go up or down, left or right, and forward or backwards.
