Proving/Verifying and Using Trig Identities

Proving/Verifying and Using Trig Identities

This course is all about Proving/Verifying and Using Trig Identities.

Upon completing this course, you will understand how to prove the Reciprocal and Quotient Identities, Odd and Even Identities, Cofunction Identities, Pythagorean Identities, Sum and Difference Formulas, Double-Angle Identities, Power Reducing Identities, Half-Angle Identities, Product-to-Sum Formulas, and Sum-to-Product Formulas.

You will be able to use the above identities to verify other trig Identities, rewrite trig expressions, find the value of trig expressions, and solve trig equations.

Finally, you will understand how to prove that a trig equation is NOT an identity.
