A unit circle diagram is a platform used to explain trigonometry. You can use it to explain all possible measures of angles from 0-degrees to 360-degrees. It describes all the negatives and positive angles in the circle. In short, it shows all the possible angles which exist.

Using the unit circle diagram, draw a line “tangent” to the unit circle where the hypotenuse contacts the unit circle. This line is at right angles to the hypotenuse at the unit circle and touches the unit circle only at that point (the tangent point). Extend this tangent line to the x-axis.
How do we use the unit circle? Locate the start place at 0°. This is our starting point. The coordinates indicated at each of the angles give us the value of the trig functions (cos and sin) for that particular angle.
