What are the sine and cosine ratios and what can we do with them?AIM:PORTFOLIO PROJECT due Friday 2/3/17Announcements: 1. Pick 3 - 5 worksheets, classwork, homework, or exam tasks, all from different units. 2. Type a two paragraph reflection about each of your work. a) Why you picked that particular piece. b) What you learned. c) What was challenging. d) What you liked/disliked. e) Why you are proud of your work. Read pp. 439-440 (§ 8-4) in the text book. Do questions p. 441 # 10-17 and show work.HW: Which trigonometric function (sine, cosine, tangent) should you use to find the angle measure of B? Explain.Do Now: After reviewing Tan relationship, we learned about SINE and COSINE. We discussed the mnemonic device, SOH-CAH-TOA. Classwork:SIN (angle) = opposite side length/hypotenuse COS (angle) = adjacent/hypotenuse TAN (angle) = opposite side length/adjacent side length Use INVERSE Trig functions when you are trying to find angle measures.
