  1. Pg. 407/423 Homework • Memorize all Trig stuff!! Test Thursday!!Study!!! • #2 x = 0.72, 5.56 • #4 no solution! • #6 x = π/8 • #8 x = 0, 3.34, π, 6.08 • #10 x = 1.47, 4.81 • #12 x = 0.98, 4.12, π/3,7π/3,5π/3, 11π/6 • #14 x = 0, π/3, π,5π/3 • #21 identity #22 identity #23 identity • #24 identity #25 cosx #26 1

  2. 7.4 Trig Identities Simplify/Verify an Expression Verify: Verify: • Simplify: • Verify:

  3. Chapter 6, 7.3, 7.6 Test Review Topics!! Applications An observer on the ground is one mile from a building 1200 ft. tall. What is the angle of elevation from the observer to the top of the building? • Applications – like the building stuff! • Finding trig values • Memorization-type stuff • Graphing trigs • Solving trigs • Proving trigs

  4. Chapter 6, 7.3, 7.6 Test Review More Practice: Things to Remember… Everything is on [0, 2π] unless otherwise noted!! Solve: 1 variable means find it 2 variables means graph Inequalities need either an interval or shaded region! • Solve: • Prove: • An angle in standard position rotates through (-2, 3). Find all trig values and Ɵ and Ɵ’ in degrees.
