A calculator to find the exact value of a coterminal angle to a given trigonometric angle. Since there are an infinite number of coterminal angles, this calculator finds the one whose size is between 0 and 360 degrees or between 0 and 2Pi depending on the unit of the given angle.

How to use the calculator 1 - Enter the angle:

  • in Degrees top input. example 745

  • in Radians middle input (decimal form): example 7.1
