Although this is a physics class, there are two fundamental math processes that we will use over and over throughout the course. Both of these are procedures you would have learned in high school math courses, though it may have been a while since you have used them on a consistent basis.

The two math procedures we will use repeatedly during the course are:
1. Use the fundamental trigonometric relations that define a right triangle, and
2. Solve a set of N equations with N unknowns.

The purpose of this module is to revisit these key procedures and give you some practice with them if you need it.
