CHAPTER 5 Trigonometric Functions and Graphs

A sine graph is a graph of the function y = sin θ. You can also describe a sine graph as a sinusoidal curve. y-2π -π π 2π 0.5-0.5-1 1 0 π_ 2 3__π 2 5__π 2-π_ 2 Period Period One Cycle 3__π 2 5__π - 2-y = sin θ θ Trigonometric functions are sometimes called circular because they are based on the unit circle.
