Trigonometry (13 Lessons) (13 lessons, $33.66)
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 â€“ 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.
