Trig Identity Calculator: Simplify Your Trigonometric Equations

This tool helps you calculate trigonometric identities quickly and accurately for any given angle.

How to Use the Trig Identity Calculator

This calculator helps to compute the values of trigonometric functions for a given angle in degrees. The available functions are sin, cos, tan, csc, sec, and cot.

Steps:

  1. Enter the angle in degrees in the “Angle” input field.
  2. Select the trigonometric function you want to calculate from the dropdown menu.
  3. Click the “Calculate” button.
  4. The result will be displayed in the “Result” field.

How It Works

The script takes the input angle in degrees and converts it into radians since JavaScript’s trigonometric functions operate with radians. The selected trigonometric function is then applied to the radians value, and the result is displayed in the “Result” field.

Limitations

Please be aware of the following limitations:

  • The angle must be entered in degrees. The script will automatically convert it to radians for calculation purposes.
  • Results beyond JavaScript’s numerical precision may result in inaccuracies.
  • The calculator does not handle complex numbers or undefined conditions (like tan(90 degrees) and sec(90 degrees)). If an input leads to infinity or an undefined result, it may output ‘Infinity’ or ‘NaN’ (Not a Number).
