Trigonometry is the study of the relationship between the angles and sides of triangles. Here you will extend this
idea to functions that have a cyclical and repeating nature. Tides, the height of a person on a Ferris wheel and
seasonal temperature can all be modeled through the use of sine and cosine functions. You will apply the basic rules
of transformations to create equations and graphs that fit data.
