How to easily memorize the Unit Circle

In this tutorial learn how to easily construct the Unit Circle by memorization.

Notice how all of the (x,y) values have a denominator of 2.

Notice the 1, 2, and 3 counting technique used for each of the numerators.

Take the square root of each numerator.

Make note of the quadrant that the point appear in to ensure the usage of proper signs.

- Quadrant I (+,+)
- Quadrant II (-,+)
- Quadrant III (-,-)
- Quadrant IV (+,-)

Make your way around the Unit Circle by just counting by 3rds (1/3) and 4ths (1/4). ** Simplify those fractions when necessary.
