Arctan Calculator

Step-by-Step Guide to Using the Arctan Calculator

The Arctan Calculator is a handy tool for calculating the arctangent of an input number and obtaining results in your preferred unit, whether degrees or radians. This guide will walk you through using the calculator to get accurate results.

Step 1: Providing the Input Value

Begin by entering a numerical value in the Input Value field. This value represents the tangent for which you wish to find the arctangent. Ensure the input value adheres to the validation requirements:

• The value must be a number.
• It must be within the range of -999,999,999 to 999,999,999.
• The field is mandatory, so you cannot leave it blank.

Step 2: Selecting the Result Unit

Next, choose the Result Unit from the options provided. This selection dictates whether the result will be in degrees or radians. The options available are:

• Degrees
• Radians

The choice selected here will affect the output format of the calculated results, such as the suffix used and the values presented.

Step 3: Viewing the Results

Once you have entered the input value and selected the result unit, the calculator will provide several results automatically. Each result is formatted to six decimal places for precision. Here’s what you can expect to see:

• Arctangent Result: This is the main result showing the arctangent of the input value. It will be in the unit you selected (degrees or radians).
• Complementary Angle: This value represents the complementary angle to the arctangent result. In degrees, it is calculated as 90° minus the arctangent angle. In radians, it is π/2 minus the arctangent.
• Supplementary Angle: This value gives the supplementary angle to the arctangent result. In degrees, it is 180° minus the arctangent angle, while in radians, it is π minus the arctangent angle.

Each of these outputs will be displayed in the unit you chose in step 2, appended with the appropriate suffix (° for degrees, rad for radians).

By following this guide, you can effectively use the Arctan Calculator to find the arctangent of any given tangent value, along with its complementary and supplementary angles, in your desired unit of measure.
