**Subject Area:**Mathematics

**Grade:**912

**Domain-Subdomain:**Functions: Trigonometric Functions

**Cluster:**Level 2: Basic Application of Skills & Concepts

**Cluster:**Model periodic phenomena with trigonometric functions. (Algebra 2 - Additional Cluster) -

Clusters should not be sorted from Major to Supporting and then taught in that order. To do so would strip the coherence of the mathematical ideas and miss the opportunity to enhance the major work of the grade with the supporting clusters.

## Problem-Solving Tasks

This problem solving task challenges students to use trigonometric functions to model the number of rabbits and foxes as a function of time.

Type: Problem-Solving Task

This problem solving task challenges students to trigonometric functions to model the populations of rabbits and foxes over time, and then graph the functions.

Type: Problem-Solving Task

In this task, students use trigonometric functions to model the movement of a point around a wheel and, through space. Students also interpret features of graphs in terms of the given real-world context.

Type: Problem-Solving Task

## Virtual Manipulative

In this online tool, students input a function to create a graph where the constants, coefficients, and exponents can be adjusted by slider bars. This tool allows students to explore graphs of functions and how adjusting the numbers in the function affect the graph. Using tabs at the top of the page you can also access supplemental materials, including background information about the topics covered, a description of how to use the application, and exploration questions for use with the java applet.
