c is much longer vector than b; it is likely that a · c is the larger.

Length Affects Dot Product

three vectors, separated by 30 degrees

The answer is not only likely, but correct.

The dot products are:

There are two properties tangled up in the dot product :

We would like to get just the angle by somehow removing the influence of length.


What is the normal method for removing the influence of length?
