Sorry, this isn't the definition of the cross product A x B. It's the definition of theVector cross product is defined as AxB = |A||B|sin(theta) where theta is the angle between A and B.

In the pdf in the link, the author never gives a geometric definition of the cross product. This product could be defined as A x B = (|A||B| sin(θ))jedishrfu said:Here's a small tutorial on it:
