1. Unit 8
The Unit Circle!

2. Unit Circle Notes

3. VERY IMPORTANT ***The Quicker you learn this stuff the better off you will be***
sin Ө = y
cos Ө = x
(x, y) = (c, s)

4. Examples sin 45º sin 270º cos 270º tan 45º sin tan cos sec 30º
csc 330º
cot 0º

5. Degree / Radian Conversion
Example:
Convert 30° into radians
Convert into degrees

6. Convert:
90º to radians
45º to radians
to degree

7. UCQ1 Everyday this week you will have a Unit Circle Quiz.
Today is just the 4 quadrant angles…you should already know these from Alg 1 
Label all four BOLD points with coordinate pt, angle measure, radian measure…

8. Lots of Practice!
