Therefore, the numerator of the first radian in the second quadrant is 5. For example, to find the numerator of the first radian in the second quadrant, you would subtract 1 from the denominator of the first radian in the first quadrant, or 6-1. It means that in order to get the numerator of each radian in this quadrant, you need to subtract 1 from the denominator of the corresponding radian in the first quadrant. 'Subtract' corresponds with the top left quadrant, or the second quadrant. It means that you'll need to memorize all of the radians in the first quadrant. 'All' corresponds with the top right quadrant in the circle, or the first quadrant. To memorize the unit circle, use the acronym ASAP, which stands for 'All, Subtract, Add, Prime.' Each word represents a different quadrant in the unit circle.

The first A, all, means that memorizing all of the angles in the first quadrants is necessary.This article was co-authored by Jake Adams and by wikiHow staff writer, Danielle Blinka, MA, MPA. The acronym ASAP helps people remember them. On such a circle, each of the radii represents an important angle. Typically, an unlabelled unit circle looks like this. ASAPĪSAP stands for “all, subtract, add, prime.” It is a mnemonic device used to remember the measure of the most important angles in a unit circle. The easy way to remember the sine and cosine values of the angles is with the left hand trick. In this case, ASAP stands for “All, subtract, add, prime.” The easy way to remember the locations of angles on the circle is with the mnemonic ASAP. In the case of the unit circle, the main things to memorize are the common angle measures in radians and where they fall on the circle and the sine and cosine values of these angles. Mnemonics are essentially tricks to help with remembering something. It requires a little bit of patience and dedication, and the process is easier with mnemonics.

Memorizing the unit circle is a lot like memorizing anything else. Unit circle memorization is necessary for mastering trigonometry.īefore continuing with the information in this section, make sure to review radian angles and the unit circle. Otherwise, learners have to pull out a unit circle and look for values every single time they do a trigonometry problem, which can be incredibly tedious. Though memorizing the unit circle takes some up-front work, it makes trigonometry a million times easier. Unit circle memorization involves memorizing the names of common angles and their corresponding sine and cosine ratios. Unit Circle Memorization – Explanation and Examples
