This document contains a trigonometry class summary for Christian Siavichay in the 2nd year of high school. It includes graphs of basic trigonometric functions over the domain [-2π,2π] and [-2π,2π]. It also contains more complex trigonometric functions that involve multiplying sin(x) by cos(nx) for various values of n. The summary is intended to help Christian study for a trigonometry test with his professor Diego Cuji.
