The circle is divided into 12 segments by radial lines that indicate angles ranging from 0\u00b0 to 360\u00b0 (or 0 to 2\u03c0 radians). The x and y axes are labeled, with key points marked at (1, 0), (0, 1), (-1, 0), and (0, -1). Each segment is highlighted with coordinates that represent the sine and cosine values corresponding to specific angles in both degrees and radians. The angles are listed in both degrees (e.g., 30\u00b0, 60\u00b0, etc.) and radians (e.g., \u03c0\/6, \u03c0\/3, etc.). The coordinates at each angle are shown in blue and red, with blue representing positive y values and red representing negative y values. The values of sine and cosine for these angles are expressed in radical form, providing precise mathematical representation.\" class=\"wp-image-6594\" srcset=\"https:\/\/www.eastcentral.edu\/learning-center\/wp-content\/uploads\/sites\/27\/2026\/07\/Unit-circle.png 625w, https:\/\/www.eastcentral.edu\/learning-center\/wp-content\/uploads\/sites\/27\/2026\/07\/Unit-circle-300x277.png 300w\" sizes=\"auto, (max-width: 625px) 100vw, 625px\" \/><\/a><\/figure>\n<\/div>\n\n\n<p>*While one can use degrees to measure angles, radians can also be used to measure angles.
