Step-by-Step Guide to Using the Inverse Tangent (arctan) Calculator

The Inverse Tangent (arctan) Calculator is a tool designed to help you compute the inverse tangent of a given number, commonly represented as arctan(x). This guide will walk you through the process of using this calculator effectively.

Step 1: Enter the X Value

  • Locate the X Value input field.
  • Enter a numerical value in the field. This value is the number for which you want to calculate the inverse tangent. Ensure that the number is within the range of -999999999 to 999999999, as specified.
  • Remember, entering this value is mandatory; the calculation will not proceed without it.

Step 2: Select the Output Angle Unit

  • Identify the Output Angle Unit selection field.
  • Choose between Radians and Degrees. The selection determines the unit in which the result will be displayed.
  • This is a required field, so make sure to select one of the options to proceed further.

Step 3: Review Your Inputs

  • Ensure that the X Value is correct and falls within the specified range.
  • Verify that the Output Angle Unit is selected according to your needs.

Step 4: Calculate the Inverse Tangent

  • Once you have entered all required information, the calculator will automatically compute the inverse tangent of the given number.
  • The result will display in the Inverse Tangent (arctan) result field.
  • The value will be formatted to six decimal places, and the unit (rad or °) will be appended according to your selection.

Step 5: Understand the Principal Value Range

  • The calculator also provides information about the Principal Value Range.
  • This field shows the range in which the angle’s principal value lies. It will indicate either -π/2 to π/2 for radians or -90° to 90° for degrees, depending on your unit selection.

This guide aims to ensure a smooth and efficient experience when using the Inverse Tangent (arctan) Calculator. By following these steps, you can easily determine the inverse tangent of any number with precision in your desired unit of measurement.
