Arctan Calculator

The Arctan Calculator is an essential online tool for anyone who frequently works with trigonometric functions. Whether you are a student, engineer, mathematician, or just someone curious about trigonometry, this calculator allows you to instantly compute the arctangent of any given number and get results in both radians and degrees. No complex formulas or manual calculations are required—just input your value, and let the tool do the work.

Understanding the arctangent function is crucial in various fields such as geometry, physics, and engineering. The arctangent function, also called atan, is the inverse of the tangent function. It is widely used to determine angles when you know the ratio of the opposite side to the adjacent side of a right triangle. Our Arctan Calculator simplifies this process and ensures accurate results every time.

How to Use the Arctan Calculator

Using this tool is simple and user-friendly. You don’t need any technical knowledge—just follow these steps:

  1. Enter the Value:
    In the input field labeled “Value,” type the number for which you want to calculate the arctangent. This can be any real number, including decimals. For example, entering 1 will calculate the arctangent of 1.
  2. Click Calculate:
    Once the value is entered, click the “Calculate” button. The calculator instantly processes your input and displays the result in two formats:
    • Radians: The standard unit for angles in mathematics.
    • Degrees: A more intuitive unit used in everyday measurements.
  3. Reset the Input:
    If you want to perform a new calculation, simply click the “Reset” button. This clears the input and result fields, allowing you to start fresh.

Example of Arctan Calculation

Let’s go through a practical example to demonstrate the usefulness of this calculator:

  • Suppose you want to find the arctangent of 0.5.
  • Enter 0.5 into the input field and click Calculate.
  • The calculator will display:
    • Arctan (Radians): 0.4636
    • Arctan (Degrees): 26.57°

This means that an angle of 26.57° (or 0.4636 radians) has a tangent value of 0.5. Such results are extremely useful in trigonometry, physics, engineering problems, and even in computer graphics.
