    \(\dfrac{\vec{a}\cdot \vec{b}}{|\vec{a}|\cdot |\vec{b}|} = \cos(\theta)\) where \(\theta\) is the angle you seek. This shoudl look very familiar.

    \[\(\dfrac{\vec{a}\cdot \vec{b}}{|\vec{a}|\cdot |\vec{b}|} = \cos(\theta)\) where \(\theta\)\] can you tell me how to read this, thanks

    Is your browser not showing the symbols? It's the inner product divided by the product of the magnitudes. Taht is the cosine fo the angle.
