The Unit Circle: A Basic Introduction The unit circle, or trig circle as it's also known, is useful to know because it lets us easily calculate the cosine, sine, and tangent of any angle between 0° and 360° (or 0 and 2 radians).

The unit circle is a circle with a radius of 1. This means that for any straight line drawn from the center point of the circle to any point along the edge of the circle, the length of that line will always equal 1.

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.
