7 Best Free Online Unit Circle Calculator Websites

Here is a list of the best free online unit circle calculator websites. A unit Circle is a circle on the coordinate system with a radius of 1 unit. Usually, the center of this circle resides at (0,0) coordinates. The unit circle is used in trigonometry as Sin is the y-coordinate and cosine is the x-coordinate.

You can calculate the unit circle from a central angle. In a right-angled triangle, it is possible to calculate trigonometric functions. By projecting a perpendicular line from the coordinates to the x-axis, you get a right-angled triangle. A unit circle calculator uses the trigonometric functions of a right-angled triangle with the hypotenuse equal to 1. The calculations give you the coordinates of the point where the angle meets the unit circle. Those coordinates are in form of sin and cosine functions.

This post covers 7 free websites with online unit circle calculators. All these calculators are quite simple to use. You just have to add the value of the given central angle into the calculator. You can use the degrees or radians measurements for the angle. With that, the calculator gives you the sin, cosine, and tangent functions which represent the coordinates of the point on the unit circle.

My Favorite Online Unit Circle Calculator

MathsIsFun.com is my favorite website on this list to calculate unit circle online. The calculator on this website is interactive. It has a circle where you can mark a central angle in real-time instead of adding the plain value. As you point to the angle, it instantly gives you the coordinates and also illustrates those coordinates on a sin-cosine graph.
