Introduction
In this lesson, we will be using power-reducing and half-angle formulas to rewrite trigonometric functions in a more convenient form.
Following successful completion of this lesson, students will be able to...
- Use power-reducing formulas to find exact values of trigonometric functions
- Use power-reducing formulas to rewrite trigonometric expressions
- Use half-angle formulas to find exact values of trigonometric functions
- Use half-angle formulas to rewrite trigonometric functions
The above objectives correspond with the Alabama Course of Study: Precalculus standards: 27.
