A unit circle is a circle that is centered at the origin and has radius 1, as shown below. If (x, y) are the coordinates of a point on the circle, then you can see from the right triangle in the drawing and the Pythagorean Theorem that x2 + y2 = 1. This is the equation of the unit circle. facebook beltz farmyardWitrynaTopic: Circle, Sine, Unit Circle. In this animation we plot . Here the label and unit on the horizontal-axis is in degrees.
