Dear friends,

Can anyone explain what themotivationis behind the vector cross product?

Why have the sine of the angle between the vectors as a multiplicand?

What makes the product another vector at right angles to the multiplicand vectors?

I mean, the guy who first decided that it should be like that must have had some reasons for it.

I can intuitively feel the idea behind dot product but this cross product baffles me.

Regards.
