This unit teaches students to recognize, graph, and write equations for sinusoidal curves with and without the use of technology. Students analyze the amplitude, period, horizontal shift, and vertical shift of sinusoidal curves and recognize the connection between the graphical and algebraic representations of a function. Activity sheets and answer keys are included. (author/sw)

Common Core State Standards for Mathematics
High School - Functions
Building Functions
Build new functions from existing functions
HSF-BF.B.3
Identify the effect on the graph of replacing f(x) by f(x) + k, k f(x), f(kx), and f(x + k) for specific values of k (both positive and negative); find the value of k given the graphs. Experiment with cases and illustrate an explanation of the effects on the graph using technology. Include recognizing even and odd functions from their graphs and algebraic expressions for them.
Trigonometric Functions
Model periodic phenomena with trigonometric functions
HSF-TF.B.5
Choose trigonometric functions to model periodic phenomena with specified amplitude, frequency, and midline.
