About This Feature
Overview
ATAN is a math and trigonometry function in WPS Spreadsheets that returns the arctangent of a number. After you enter one numeric argument, the function returns the corresponding angle in radians, which is useful for trigonometric calculations, angle conversion, and spreadsheet modeling.
Core tasks include:
- Insert ATAN from the Insert Function dialog.
- Type
=ATAN(...)directly in a cell or in the formula bar. - Review the syntax
ATAN(number)and its parameter meaning before entering the formula.
Common use cases include trigonometry study, engineering calculations, and worksheet modeling. It helps you calculate inverse tangent values faster and reduce formula entry mistakes.
System Requirements
| Item | Requirement |
|---|---|
| Operating system | A Windows device that can run WPS Office normally |

Compare with Alternatives
| Dimension | WPS | Microsoft | Notion | Adobe | |
|---|---|---|---|---|---|
| Capability Summary | WPS supports ATAN(number) in spreadsheets and lets you insert the function from the function dialog or type it directly in a cell. | Excel provides ATAN(number) and returns the arctangent in radians in the range -pi/2 to pi/2. | Google Sheets provides ATAN(value) and returns the inverse tangent in radians, with DEGREES available for angle conversion. | Notion's formula help explains general formula syntax and numeric functions, but no official ATAN help entry was identified on the referenced page. | Adobe Acrobat Sign supports calculated fields and math expressions in forms, but the referenced help page does not show an ATAN function entry. |
| Official Source | — | ATAN function | ATAN | Formula syntax & functions | Add calculated fields to a form |
Advantage: WPS provides a direct spreadsheet function workflow with both dialog-based insertion and direct formula entry.
Overall Conclusion
For spreadsheet-based inverse tangent calculations, WPS, Microsoft Excel, and Google Sheets all provide clear ATAN syntax and usage guidance. Notion and Adobe focus more on general formulas or form calculations in the referenced help pages, so WPS is a more direct fit for worksheet-based function entry and calculation.
Use Cases
| No. | Scenario | Suitable for | Main challenge | How ATAN helps |
|---|---|---|---|---|
| 1 | Trigonometry practice | Students and teachers | You need to verify inverse tangent results quickly | Enter =ATAN(number) in a cell to calculate directly |
| 2 | Engineering angle conversion | Engineers and technical users | You need a radian result before further conversion | Use ATAN first, then continue with related formulas |
| 3 | Batch calculations | Data-processing users | Manual calculation across many rows is inefficient | Enter the formula once and fill it down |
| 4 | Function learning and checking | New spreadsheet users | The parameter format is unfamiliar | Use Insert Function to review syntax and parameter details |
| 5 | Formula troubleshooting | Everyday office users | Formula results look incorrect | Check parameter types, separators, and references |
