$\vec{v_{1}} \cdot \vec{v_{2}} =|\vec{v_{1}}||\vec{v_{2}}|\cos(\theta)$ $\vec{v_{1}} \cdot \vec{v_{2}} = x_{1} * x_{2} + y_{1} * y_{2} + z_{1}*z_{2}$

Hvis mangler et tal kan man bruge denne formel: $\vec{v_{1}} \cdot \vec{v_{2}} = x_{1} * x_{2} + y_{1} * y_{2} + z_{1}z_{2} = \vec{v_{1}} \cdot \vec{v_{2}} =|\vec{v_{1}}||\vec{v_{2}}|*\cos(\theta)$
