3.8 Trig Equations (cont.) Warm-up (IN) 1.Solve: Learning Objective: to continue to learn techniques that are useful in solving trig identities, including using identities to simplify an equation before attempting to solve it and being able to identify the restrictions to solutions and why a possible solution can or can't be part of a final solution.

2
Notes! Ex 1 – Solve the equations on the interval

3
Not factorable! So, try an identity!

4
Not possible! Not factorable! So, no solution!

5
Square both sides! When you square both sides, you MUST check for extraneous solutions!

6
Ex 2 – Solve using calculator

7
HW – p.281 #5-9,11-15, 21,22,32,53-55 Out – solve Summary – the hardest and easiest parts of chapter 3 are… Don’t forget about POW!! Toys for Tots!
