Frequently, especially in trigonometry, the unit circle is the circle of radius 1 centered at the origin (0, 0). Calculators and graphing software are helpful for finding sines and cosines if the proper procedure for entering information is known. Written by tutor shujen w.

It can be seen from the graph, that the unit circle is defined as having a radius ( r ) = 1.

This is how the unit circle is graphed, which you seem to understand well. The unit circle, in it's simplest form, is actually exactly what it sounds like: Compare the graphs of sine, cosine, and tangent. Unit circle and sine graph.
