I teach the basics of Adobe Photoshop, both full-version and Photoshop Elements. This includes the interface and how it works; the Tools, Menus, and Filters; the different panels, such as History, Actions and and especially the Layers Panel. I can explain Layers and how they work, as well as Masks.
...The courses I've taught include precalculus. My PhD is in applied mathematics. The basic concepts of trigonometry are constructed and derived from geometric principles, but once the student has gone through the formal definitions and constructs, trigonometry is then seen to fit into an enormous class of problems of both statics and dynamics.
