Slide2Section 5.1Simplifying More Trig Expressions

Slide3Fundamental Trigonometric Identities:Reciprocal Identities: Quotient Identities: Pythagorean Identities: Cofunction Identities:

Slide4Even / Odd Identities:

Slide5Trig Identities• Any relationship that is true for all values of the variable for which each side is defined is called an  identity .    • We can use trig identities to simplify trig expressions, prove other identities and solve more complex trig equations.

Slide6Strategies for Simplifying Trig Expressions:1. 2. 3. 4. 5.

Slide7We can factor trigonometric expressions, too!Ex 1: Factor each trig expression A. B. C.

Slide10Ex 4: Simplify by factoring:

Slide13Ex 7: Simplify by factoring
