PeriodicFunctionsØ  Flip to the side of your guided notes that reads “Parent

Sine Function.” Ø  Using your Unit Circle, complete the y-values of the

table for the function y = sin x. (We will do the Hirst one together)

Ø  Plot the table of values onto the coordinate plane and connect the dots. We must label the axes, the x-values represent the radians and count by ½ on the y-axis.

Ø  Identify the maximum, minimum, midline, amplitude, and period.

PeriodicFunctionsØ  Flip to the side of your guided notes that reads “Parent

Cosine Function.” Ø  Using your Unit Circle, complete the y-values of the
