Solve real-world problems involving applications of trigonometric functions using graphing technology when appropriate.
Remarks
Example: The number of hours of daylight varies through the year in any location. A graph of the number of hours of daylight throughout the year is in the form of a sine wave. In a certain location the longest day of 14 hours is on Day 175 and the shortest day of 10 hours is on Day 355. Sketch a graph of this function and find its equation. Which other day has the same length as July 4 (Day 186)?General Information
Subject Area: X-Mathematics (former standards - 2008)
Grade: 912
Body of Knowledge: Trigonometry
Idea: Level 3: Strategic Thinking & Complex Reasoning
Standard: Trigonometric Functions - Extend the definitions of the trigonometric functions beyond right triangles using the unit circle, and measure angles in radians as well as degrees. Draw and analyze graphs of trigonometric functions (including finding period, amplitude, and phase shift), and use them to solve word problems. Define and graph inverse trigonometric functions, and determine values of both trigonometric and inverse trigonometric functions.
