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 2π depending on the unit of the given angle.
How to use the coterminal angle calculator
1 - Enter the angle:
then press the button "enter".
- in Degrees input. example 745
- in Radians input, enter angle as a fraction of π: example 12π/5
