Unit Circle Values Chart
What is Unit Circle Values Chart?
A Unit Circle Values Chart is a graphical representation of the values of sine, cosine, and tangent for all angles on a unit circle. In mathematics, the unit circle is a circle with a radius of 1 unit, centered at the origin of a coordinate plane. The chart provides a visual reference for the trigonometric functions at different angles, helping users to solve trigonometric equations and understand the relationships between angles and their corresponding values.
What are the types of Unit Circle Values Chart?
There are different types of Unit Circle Values Charts available, each serving a specific purpose. Some common types include:
Complete Unit Circle Values Chart: This chart displays the values of sine, cosine, and tangent for all angles from 0 to 360 degrees or 0 to 2π radians.
Inversed Unit Circle Values Chart: This chart shows the inverses of sine, cosine, and tangent values for angles on the unit circle.
Unit Circle Trigonometric Identities Chart: This chart lists the trigonometric identities for various angles on the unit circle.
Blank Unit Circle Chart: This chart provides a blank template for users to fill in the values of sine, cosine, and tangent for specific angles.
How to complete Unit Circle Values Chart
Completing a Unit Circle Values Chart is a relatively simple process. Here are the steps to follow:
01
Start by drawing a circle with a radius of 1 unit and label the center as the origin (0, 0).
02
Divide the circle into four quadrants, labeling them as the first, second, third, and fourth quadrants in a counterclockwise direction.
03
Identify the key angles in each quadrant: 0°, 30°, 45°, 60°, and 90°.
04
For each angle, determine the corresponding values of sine, cosine, and tangent using the mnemonic SOH-CAH-TOA (Sine = Opposite/Hypotenuse, Cosine = Adjacent/Hypotenuse, Tangent = Opposite/Adjacent).
05
Record the values in the corresponding sections of the chart.
06
Continue this process for all angles from 0 to 360 degrees or 0 to 2π radians.
07
Once completed, review the chart to understand the patterns and relationships between angles and their trigonometric function values.

Right 30 degreesMoreSo I'm going to start with zero degrees. And every big gap is a 30 degree gap. Right 30 degrees every little gap is a 15 degree cap. So really have to do is just add 15 here so 30 15 is 45.
How do you use the unit circle chart?
Unit circle with quadrants added. Quadrant 1 is top right, quadrant 2 is top left, quadrant 3 is bottom left and quadrant 4 is bottom right. We can use (x, y) coordinates to describe any point along the outer edge of the circle. The x-coordinate represents the distance traveled left or right from the center.

How do you do unit circle charts?
In a unit circle, you measure the positive sides of the circle by utilizing the first side of the positive x-axis. At that point, you will instantly move to the terminal side of the circle. The unit circle chart shows the positive points named in radians and degrees.
