10+ Unit Circle Diagram. Unit circle diagram is provided in each worksheet for reference. The unit circle makes it possible to easily calculate the sine, cosine, or tangent of angles that fall between 0° and 360°.

The unit circle is often denoted s1 while the generalization to higher dimensions is the unit sphere. Extending soh cah toa so that we can define trig functions for a broader class of angles practice this lesson yourself on khanacademy.org right now: You now have a handy guide to help you see the relationships between angles.

The unit circle is often denoted s1 while the generalization to higher dimensions is the unit sphere. Frequently, especially in trigonometry, the unit circle is the circle of radius 1 centered at the origin (0, 0) in the cartesian coordinate system in the euclidean plane.
