3.3 Trig Identities Warm-up (IN) 1.True or False: 2.True or False: Learning Objective: To understand that establishing trig identities provides the skills necessary to accomplish tasks in higher level mathematics and to develop skills in problem solving, systematically evaluate and establish each identity using prior knowledge, and develop patience when dealing with more intricate math problems. True NTBK test next class!

NOTES And the identities are…. Quotient identities Reciprocal identities Pythagorean identities Odd-even identities You need to KNOW these!!

Ex 1 – Establish the identity: “Fix” the complex side so it looks like the other side!

Factor!

HW – pg. 243 #19-25,41-45,70-73,83,84 Out – Write the 1 st 4 identities that pop into your head Summary – This lesson makes me think…about identities. Don’t forget about POW!! Look at bottom of pg 242 for suggestions!
