# Vector Projection

## An interactive 3D plot

You can specify two vectors v and w; you may also multiply v by a scalar $$\alpha$$ and w by a scalar $$\beta$$ by adjusting the sliders (by default $$\alpha$$ and $$\beta$$ are set to 1). The vector $$\alpha$$v will be plotted in blue, $$\beta$$w will be plotted in green, and the projection $$proj_vw$$ will be plotted in red. Optionally, you can view the right-angled triangle determined by w and $$proj_vw$$.
