I'm re-visiting calculus again, and I've stumbled onto the concepts of scalar and vector projections in the vector chapter. While keeping in mind which equation to use for what projection is quite doable, I cannot seem to see the purpose of keeping scalar and vector projections in mind. Can anyone help clarify or state these two things in layman's terms? Much thanks in advance.(adsbygoogle = window.adsbygoogle || []).push({});
