Understanding the counting aspects of the degrees and radians allows you to easily mark up your entire Unit Circle with those components.
Knowing the relationship between our SRTs and the coordinates can help you easily reproduce any forgotten coordinate value in the first quadrant.
And once you have the first quadrant, you can use it and your understanding of quadrant symmetry and quadrant signs to complete the remaining three quadrants.
Please watch the following video where I will demonstrate how this knowledge of quadrant symmetry and signs allows us to easily complete our Unit Circle.
As with all things, practicing completing the Unit Circle is key for success. Please Quiz yourself at the following site Unit Circle Quiz and download the following Blank and Completed Unit Circle documents for your additional practice. Good Luck!
