Clipart illustration of the unit circle commonly used when teaching trigonometry. The unit circle is a circle centered at the origin with a radius of 1 unit. It is a tool used when teaching the values of the trigonometric functions (sine, cosine, tangent, cotangent, secant, and cosecant) at all points on the circle.
