How to fill out unit circle practice problems

How to fill out unit circle problems:

1. Start by drawing a circle in the coordinate plane with a radius of 1.
2. Divide the circle into four quadrants, labeling them as the first, second, third, and fourth quadrants in a counterclockwise direction.
3. Identify the angles you need to solve by using degrees or radians.
4. Memorize the values of a few key angles on the unit circle, such as 0°, 30°, 45°, 60°, 90°, 180°, and so on.
5. Determine the coordinates of each angle by using the sine and cosine functions.
6. Fill out a table or chart with the angle, its coordinate points, and any other relevant information needed for the problem.
