About This Feature
Overview
ACOS returns the arccosine of a number in WPS Spreadsheet. Its syntax is ACOS(number). You can insert it from the Insert Function dialog, type the formula directly in a cell or the formula bar, and review its syntax and parameter guidance before applying it in a worksheet.
Core tasks include:
- Insert
ACOSfrom the Insert Function dialog - Type
=ACOS(...)directly in a cell or the formula bar - Review the
ACOS(number)syntax and parameter guidance
Common use cases include trigonometric calculations, intermediate steps before angle conversion, and checking a formula before filling it across multiple cells.

Compare with Alternatives
| Dimension | WPS | Microsoft | Notion | Adobe | |
|---|---|---|---|---|---|
| Capability Summary | Supports ACOS(number) in WPS Spreadsheet, with insertion through the Insert Function dialog or direct formula entry, plus syntax guidance in the function workflow. | Excel supports ACOS(number), returns the arccosine in radians from 0 to pi, and suggests using DEGREES to convert the result. | Google Sheets supports ACOS(value), requires the value to be between -1 and 1, and returns the inverse cosine in radians. | Notion’s official formula reference explains formula syntax and supported functions, but no official ACOS function entry was identified in the retrieved help content. | Adobe Acrobat Sign supports calculated fields and a set of math functions for forms, but no official ACOS function entry was identified in the retrieved help content. |
| Official Source | — | ACOS function | ACOS - Google Docs Editors Help | Formula syntax & functions | Add calculated fields to a form |
Advantage: WPS supports both guided insertion and direct worksheet entry for the same spreadsheet function workflow, which is practical for users moving from function lookup to repeated formula input.
Overall Conclusion
For inverse cosine calculations in spreadsheets, WPS, Microsoft Excel, and Google Sheets all provide an ACOS function. WPS fits well into a worksheet-based workflow because it supports both guided function insertion and direct formula entry in the same editing environment.
Use Cases
| No. | Scenario | Suitable For | Main Need | How ACOS Helps |
|---|---|---|---|---|
| 1 | Learning inverse cosine calculations | Students and teachers | Need a quick way to return an arccosine result | Search for ACOS in the Insert Function dialog and fill in the parameter |
| 2 | Fast formula entry | Office users and data workers | Already know the function name and want faster input | Type =ACOS(...) directly in a cell or the formula bar |
| 3 | Syntax confirmation | First-time function users | Need to confirm the parameter format | Review the ACOS(number) syntax and help entry |
| 4 | Pre-check before batch fill | Finance and analysis users | Want to avoid formula mistakes before filling down | Verify the formula in one cell before copying it |
| 5 | Preparation for angle conversion | Engineering and research users | Need a radian result before later conversion | Use ACOS first, then continue with angle conversion functions |
