### Important Concepts for This Unit

Many phenomena in nature are cyclical, such as the seasons, the tides, and sound,  The sinusoidal functions defined by right triangles can be extended to circles and are vital in understanding any phenomena that repeats over some interval. In this unit we will learn how the sine, cosine, and tangent functions can be used to model cyclical phenomena. The standards that will be assessed in this chapter are
