Trig: Simplifying and Proving Identities 350

This lesson is part of the series: Trigonometry

This 64 minute trigonometry lesson will show you how to simplify and prove trigonometry expressions using the trig:
- reciprocal identities
- quotient identities
- Pythagorean identities

Sample problem: Prove sec Theta – cos Theta = sin Theta x tan Theta

In addition to the trig identities the simplifying process will use will use algebra skills (finding a common denominator, multiplying, factoring, reciprocal ratios).

This lesson contains explanations of the concepts and 18 example questions with step by step solutions plus 7 interactive review questions with solutions.
