- 1. Exact Angle - Multiples and x-y Plane In Degrees , 60 , 45 , 30 90 - Multiples 60 - Multiples o o o 120 o o 180 o o o 45 - Multiples 30 - Multiples o 135o o 150o o 210o o 315o
- 2. Exact Coordinates for P( ) Recall, P( ) = (cos , sin ) P(180
- 3. x=y 1 Use a + b = c = y r x (- , ) ( , ) (- ,- ) ( ,- ) Conclusion: P( ) = (+ - ,+ - ) tan( ) = +1 -
- 4. Conclusion: P( ) = (+ - , + - ) + -
- 5. 1 1 coordinates of 30 Conclusion: P( ) = (+ - ,+ - )
