This tool calculates the arctangent value for a given number instantly.
How to Use the Arctan Calculator
This calculator allows you to compute the arctangent (inverse tangent) of a given value. Follow these steps to use the calculator:
- Enter a numeric value in the input field labeled Enter value (x).
- Click the Calculate button.
- The result will be displayed in the Results section below the input form.
How the Calculator Works
The script parses the input value to ensure it is a valid number. If the input is invalid, an error message will be displayed. If the input is valid, it calculates the arctangent of the input value using the JavaScript Math.atan() function and displays the result in a table format.
Limitations
This calculator is designed to compute the arctangent for a single numeric value at a time. The input must be a valid finite number. Note that this tool does not support complex numbers or special mathematical functions beyond the standard arctangent computation.
