Using the Half Angle Trigonometry Calculator

To use the tool to find the results of the trigonometric functions for half a given angle, enter the angle, choose how its measured (degrees or radians) and compute.

  • Angle: Enter the angle which you'd like to compute the functions using – the tool will take half
  • Degrees or Radians: Choose which units you use to measure the angle

Where results are undefined, you'll see "NaN".

Next, see the double angle calculator, or the triple angle calculator, or trigonometry functions calculator, or inverse trigonometry calculator.
