The cross product
- David Richeson
The cross product of two vectors u and v in is a vector in that is perpendicular to both u and v. It is denoted uxv. Use the applet below to discover the basic properties of the cross product. The questions below the applet are intended to guide your discovery. Note: in the applet below, the vectors u and v live in . The green plane contains the two vectors u and v and uxv is perpendicular to the green plane. "Up" from the green plane corresponds to "out" of the computer display.
