DISCUSS: Phases of Sine The phase of a sine curve y = sin(kt + b) represents a particular location on the graph of the sine function y = sin t. Specifically, when t = 0, we have y = sin b, and this corresponds to the point (b, sin b) on the graph of y = sin t. Observe that each point on the graph of y = sin t has different characteristics. For example, for t = π/6, we have
