Sine And Cosine For Angles 0 To 360 Degrees
Overview
Sine and cosine are not limited to the angles inside a right triangle. By spinning a point around a circle you can define them for every angle from 0 to 360 degrees, and their graphs reveal a smooth, repeating wave.
In this lesson you will find the sine and cosine of angles from 0 to 360 degrees, recognize their wave-shaped graphs, and use symmetry to relate angles in different quadrants.
Objectives
- Use the sine and cosine of angles between 0 and 360 degrees, including the relationship between the sine and cosine of supplementary angles.
