Domain - Trigonometric Functions
Cluster - Model periodic phenomena with trigonometric functions.
[MIII.F-TF.B.5] - Choose trigonometric functions to model periodic phenomena with specified amplitude, frequency, and midline.*
- Midline
In the graph of a trigonometric function, the horizontal line halfway between its maximum and minimum values. - Periodic phenomena
Naturally recurring events, for example, ocean tides, machine cycles. - Trigonometric function
A function (as the sine, cosine, tangent, cotangent, secant, or cosecant) of an arc or angle most simply expressed in terms of the ratios of pairs of sides of a right-angled triangle.
[MI.F-IF.C.7.e] -
Graph exponential functions, showing intercepts and end behavior.*
[MI.F-BF.B.3] -
Identify the effect on the graph of replacing f(x) by f(x) + k, kf(x), f(kx), and f(x + k) for specific values of k (both positive and negative); find the value of k given the graphs. Include linear and exponential models. (Focus on vertical translations for exponential functions). Utilize technology to experiment with cases and illustrate an explanation of the effects on the graph.
[MIII.F-IF.B.4] -
For a function that models a relationship between two quantities, interpret key features of graphs and tables in terms of the quantities, and sketch graphs showing key features given a verbal description of the relationship. Key features include: intercepts; intervals where the function is increasing, decreasing, positive, or negative; relative maximums and minimums; symmetries; end behavior; and periodicity.*
[MIII.F-TF.A.2] -
Explain how the unit circle in the coordinate plane enables the extension of trigonometric functions to all real numbers, interpreted as radian measures of angles traversed counterclockwise around the unit circle.
