Unformatted text preview: 1.8 Trig Functions of Special Angles Part 2 Wednesday, September 07, 2011 7:52 AM Agenda: 1. Classwork 2. Lesson: 1.8 Trig Functions of Special Angles Part 2 ______________________________ Lesson: 1.8 Trig Functions of Special Angles Part 2 Goal: Learn and apply the trig functions of special angles It is my expectation that you will memorize the trig functions of special angles. I will give you some strategies for learning these values. We will have a no-reference, nocalculator test on these values next block day. If we know the trig values of the special reference angles and the sign of the trig function in a particular quadrant, then we know the values of the trig functions of the special angles! Let's start with this chart (Special Reference Angles) These values come from the chart you filled out in your homework from yesterday. We will refer back to this a lot! Now, what about the signs or Ch_1 Page 1 of the trig functions? So putting this all together… 1. Find θ' (reference angle). 2. What is the value of the trig function (from reference angle)? 3. What quadrant are we in? ______________________________ Examples Find the values of all 6 trig functions for the given angle measure θ. If , find all the values of θ. Ch_1 Page 2 and and Ch_1 Page 3 ...
