Projection

Learned in Math 115

Projection Equation:

proj${}_{\overrightarrow{v}}\overrightarrow{u}$ = $\frac{\overrightarrow{u}\cdot \overrightarrow{v}}{\mid \overrightarrow{v}{\mid }^2}$ $\overrightarrow{v}$

$\perp$ $\overrightarrow{u}$ = $\overrightarrow{u}$ - proj_\overrightarrow{v}^ \overrightarrow{u}
