AIM: What are the sine and cosine ratios and what can we do with them?
Announcements: PORTFOLIO PROJECT due Friday 2/3/17
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.
HW: Read pp. 439-440 (§ 8-4) in the text book. Do questions p. 441 # 10-17 and show work.
Do Now: Which trigonometric function (sine, cosine, tangent) should you use to find the angle measure of B? Explain.
Classwork: After reviewing Tan relationship, we learned about SINE and COSINE. We discussed the mnemonic device, SOH-CAH-TOA.
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.
