👉 Learn about the unit circle. A unit circle is a circle which radius is 1 and is centered at the origin in the cartesian coordinate system. To construct the unit circle we take note of the points where the unit circle intersects the x- and the y- axis. The points of intersection are (1, 0), (0, 1), (-1, 0) and (0, -1). There are other points which are necessary to master in the unit circle. The unit circle is a very helpful tool in the evaluation of the six trigonometric functions of some angles.
