What do you get when you cross an elephant with a peanut?

Elephant peanut cosine theta.
I don't 'get it' ...I'm 'math impaired'..remember?

A cross-product is a "vector product". You "multiply" two vectors and the
output is another vector, whose direction is at right angles to the other
two vectors, and whose magnitude is equal to the product of the magnitude
of the vectors and the sine of the angle between them. (I just looked this
up. The answer William gave is in error. The cosine is used for the dot
product.)
