Using the Double Angle Trigonometry Calculator
To use the tool to find the results of the trigonometric functions for double 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 double
- Degrees or Radians: Choose which units you use to measure the angle
Where results are undefined, you'll see "NaN".
