Enter the Angle of the Unit Circle in given Field

Unit circle calculator is an extremely handy online tool which computes the radians, sine value, cosine value and tangent value if the angle of the unit circle is entered. A unit circle or a trigonometry circle is simply a circle with radius 1 unit.

Using the unit circle calculator is easy and quick. Follow the below-given steps to use the unit circle calculator tool.

For an angle 45 degrees, the calculator will give the output as:

Cosine 45° = 6.123233995736766 x 10 -17

A unit circle has a radius of 1. The general equation of a circle is:

As the radius of the unit circle is 1, the formula of unit circle or its equation becomes:

A unit circle can be used to easily calculate the cosine, sine, and tangent of any angle between 0 and 360 degrees.

In a unit circle, the angles measured in clockwise direction have positive values and angles measured in anticlockwise direction have negative values.

The equation of a unit circle is x 2 +y 2 =1
