OK,
WikiIsNotaDictionary, but there seem to be a few math definitions around.
The
CrossProduct of two vectors is a vector perpendicular to both which has a length equal to the area of the parallelogram defined by them, and points in a direction such that it obeys the right-hand rule. That makes the
CrossProduct anti-commutative.
- a x b = -b x a
- (ka) x b = k(a x b)
- a x a = 0
- What do you get if you cross a sheep with a kangaroo?
- A woolly jumper
- What do you get if you cross a mountaineer with a mosquito?
- Nothing - you can't cross a scalar and a vector.
