Unit 4 – Trigonometry Date Nov. 20 Nov. 21 Nov. 24 Topic Primary Trig Ratios – Finding Sides and Primary Trig Ratios – Finding Angles and Solving Right-Triangles I know what SOH CAH TOA stands for I can accurately label the sides of a triangle from a given angle I can use sine, cosine or tangent to solve the length of side of a right triangle Primary Trig Ratios – Finding Sides and Primary Trig Ratios – Finding Angles and Solving Right-Triangles I can use sine, cosine or tangent to solve for unknown angles I can solve for ALL unknown side lengths and angles in a rightangled triangle Problem Solving I can set up diagrams from word problems involving triangles I can use SOH CAH TOA to determine the required measurement (Side length or angle) Work Period and Review Nov. 25 Nov. 26 Nov. 27 Nov. 28 Dec. 1 Dec. 2 Dec. 3 Dec. 4 (buy-out dance) work period if more than half class missing Mid Unit Quiz Sine Law I can use the sine law to find missing side lengths and angles in acute triangles Cosine Law I can use the cosine law to find the missing side length in a triangle when the other two sides and their contained angle are known I can use the cosine law to find a missing angle when the three side lengths are known. Solving Oblique Triangles + Word Problems I can solve for ALL unknown side lengths and angles in an oblique triangle I can set up diagrams from word problems involving triangles I can use SOH CAH TOA, Sine Law, and Cosine Law to determine the required measurement (Side length or angle) Work Period Test Homework Questions from Notes: p. 104 – 106 (Questions from lesson 3A) p. 496 #9 – 11 (The 2nd method for #11 is Pythagorean theorem) Questions from Notes: p. 107 – 109 (Questions from lesson 3B and 3C) p. 496 # 6, 7 Notes: Pg 113 + p. 509 #1-9 See above p. 522 #12 – 14, 15, 17, 18 Pg 549 #1-4, 6-10, 12 Pg 566 #2-8, 10 Handout (solving triangles) + p. 510 #17, p. 550 #15, p. 567 # 9, 13, p. 575 # 10, 17 + Handout (problem solving)+ p. 582 #4 – 12 See above Done
