Objectives
- Use the sum and difference, the double-angle, and power-reducing formulas for cosine, sine, and tangent and the Pythagorean identities.
- Symbolically verify identities by using various trig identities.
- Find all solutions to a trigonometric equation.
- Use the law of sines and/or the law of cosines to solve non-right triangles.
- Solve applications that require the use of trigonometry to find a side or angle.
