Worked Out Examples and Notes

1-20-22

Review for summative assessment on use of sum, difference, and double angle rules for sine, cosine, and tangent
- Derive the formulas for the double angles of sine of an angle and cosine of an angle
- Use the sum, difference, and double angle formulas to rewrite as a sum or difference of a pair of products of trigonometric ratios, or as a ratio of trigonometric expressions, or as a product trigonometric expressions
- Use a given trigonometric ratio in a specific quadrant to apply the sum, difference, and double angle rules
- Be able to use a pair of trigonometric ratios in specified quadrants to apply the sum, difference and quotient, rules

1/21/22
