Unit Cricle Chart - Brief Explanation of Unit Circle Chart

unit circle  See description below In mathematics, a unit circle is a circle with a radius of one In trigonometry, the unit circle is the circle of radius one centered The unit circle chart shows the position of the points along the circle that are formed by dividing the circle into equal parts

We will use these coordinates in later sections to find trigonometric functions of special angles on the unit circle x 1 1 45o 2 2  Lesson The unit circle is a circle of radius one, centered at the origin, that summarizes all the 30-60-90 and 45-45-90 triangle relationships
