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.

Steps to Use Unit Circle Calculator

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

  • Step 1: Enter the Angle of the Unit Circle (in degrees) in the first input box.
  • Step 2: Click on “Solve”
  • Step 3: Check the “Radians”, “Sine Function Value”, “Cos Function Value”, and “Tan Function Value” for the entered angle in the output boxes.

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

Radians = 0.785

Sine 45° = 0.707

Cosine 45° = 6.123233995736766 x 10-17

Tangent 45° = 1.000

What is the Formula and Equations of Unit Circle?

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

(x−h)2+(y−k)2=r

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

x2+y2=1
