In this episode, we're pushing towards final time, and also towards episode 100, so we're taking stock of where we've been, where we are, and where we're going. For midterms and finals, it's so important to make sure the basics are under control, so here we roll through a little 3 question quiz for the following topics: Coordinate Systems, Sine & Cosine, SOHCAHTOA, Vector Components, Vector Operations. If you don't have the questions asked in this episode locked down please, please do yourself a favor and grab the apps or the bundle. This stuff is so important to know absolutely cold for your big exam!
