Arctan Calculator (Inverse Tangent)
Find out the inverse tangent with this arctan calculator.
What Arctan Calculator (Inverse Tangent) does
An arctan calculator determines the angle whose tangent equals a given numerical input. Users enter a single value and receive the corresponding angle, with the option to display the result in either degrees or radians. The tool also provides a reference graph and a table of common values, such as arctan(0) and arctan(1), to aid understanding of the function's behavior. It serves as a straightforward solution for anyone needing to convert a tangent ratio into an angular measurement without manual computation.

Arctan Calculator (Inverse Tangent) FAQ
- What is the range of angles returned by the arctan calculator?
- The calculator returns the principal value of the inverse tangent, which is always between −π/2 and π/2 (−90° and 90°).
- Can I input negative numbers into the arctan calculator?
- Yes, the tool accepts any real number, including negatives, and will return a negative angle within the principal range.
- How does arctan differ from the regular tangent function?
- Arctan is the inverse of tangent; it takes a ratio and returns the angle that produces that ratio, whereas tangent takes an angle and returns the ratio.
- Is the arctan calculator accurate for very large or very small numbers?
- The tool maintains accuracy across various input ranges, providing precise trigonometric results for both large and small numerical values.
