Quickly find inverse cotangent values in degrees or radians. Simple tool that gives accurate results every single time.
| x | Inverse Cotangent (rad) | Inverse Cotangent (deg) |
|---|---|---|
| 1 | 0.78539816339745 | 45 |
| 0 | 1.5707963267949 | 90 |
| 2 | 0.46364760900081 | 26.565051177078 |
The inverse cotangent is calculated using the formula:
cot⁻¹(x) = arctan(1/x) for x ≠ 0.
For x = 0, cot⁻¹(0) = π/2 radians or 90°.
1. Enter any real number in the input field labeled "Enter Value".
2. Press the "Calculate" button.
3. View the result above the form in both radians and degrees.
4. Optionally download results in CSV or PDF format.
The inverse cotangent, also written as cot⁻¹(x), is the angle whose cotangent equals x. It is widely used in trigonometry, geometry, and calculus. Unlike arctangent, it has a unique behavior at zero. The cotangent function is the reciprocal of tangent, which means cot(x) = 1/tan(x). Therefore, cot⁻¹(x) can be calculated using arctangent formula arctan(1/x). This calculator allows for quick computation without manual work. It works for positive, negative, and zero values. Results are shown in both degrees and radians for convenience. The example data table demonstrates typical values for quick reference. This is helpful for students and professionals alike. Downloading in CSV or PDF enables sharing and record keeping. The tool is simple, fast, and accurate for any real number.
