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
 in Radians bottom input (fractional form): example 13Pi/3
then press the button "enter" on the same row.
