Use your hand as an easy way to remember the unit circle. Use this math trick to help memorize the unit circle.

How to find the value of Quadrant 1 of the Unit Circle

The first coordinate is always Cosine and the second is Sine

Step 1. Let's find cosine first. Starting at your thumb each finger will have a square root and a degree. The thumb will be 90 degrees, and then 60 degrees,45 degrees, 30 degrees,ending with your pinky being 0 degrees

Step 2. Which ever finger you fold, the number of fingers above the finger will tell you the number of square roots which represents the first coordinate,over 2.which is represented by the palm of your hand.

Step. 3. The number of fingers below the folded finger represents the sine.

Step 4. Repeat this for each finger and you will have quadrant 1 of the unit circle.
