Unit 7 – Trigonometric Methods

April 2019 G-SRT.6 I can use similarity to explain how side ratios in right triangles are related to the angles of the triangle. G-SRT.7 I can explain and use the relationship between the sine and cosine of complementary angles (i.e. sin 30 o = cos 60o). G-SRT.8 I can use trigonometric ratios to solve real-world problems involving right triangles. I can use Pythagorean Theorem to solve real-world problems involving right triangles. G-SRT.9 (+) I can derive the formula A=1/2absin(C) for the area of a triangle. G-SRT.10 (+) I can prove the Law of Cosines and use it to solve problems. I can prove the Law of Sines and use it to solve problems. G-SRT.11 (+) I can use Law of Sines and Cosines to solve problems.
