About This Feature

Overview

ACOS is a math and trigonometric function in WPS Sheets that returns the inverse cosine result for an input value. When you enter the formula, syntax guidance shows parameter requirements and examples so you can complete formula editing more quickly.

Core capabilities include:

Enter =ACOS( to view syntax guidance
Type the formula in a cell or in the formula bar and return a result
Support cross-worksheet references and nested calculations
Recalculate automatically when source data changes

This function is useful for trigonometric calculations, data analysis, and spreadsheet training.

System Requirements

Item	Requirement
OS	A Windows device that can run WPS Office normally
App version	It is recommended to use the latest version of WPS Office
Network	Local formula calculation does not require a network connection; downloading, installation, and account-related actions require internet access
Other	You need to open WPS Sheets and edit worksheet cells

Download & Installation

Before using the ACOS function, install WPS Office on your Windows device and open WPS Sheets.

Dimension	WPS	Microsoft	Google	Notion	Adobe
Capability Summary	Supports ACOS and other functions in WPS Sheets, with syntax guidance, cross-worksheet references, nested calculations, and automatic recalculation.	Microsoft Word lets users use formulas in table cells, supports functions and cell references, and allows manual or document-open updates, but the scenario is mainly document tables rather than a spreadsheet grid.	Google Sheets is an online spreadsheet for managing, visualizing, and analyzing data, and Google states that Gemini in Sheets can create formulas to help with calculations.	Notion formulas perform calculations with database properties, built-ins, and functions, and the results apply to database properties rather than traditional spreadsheet cells.	Adobe Acrobat supports calculated fields in PDF forms, including predefined calculations such as sum, product, average, minimum, and maximum, but it is designed for PDF form workflows rather than spreadsheet formulas.
WPS Advantages	Advantage: Better aligned with desktop spreadsheet cell-based formula entry; Distinct: combines syntax guidance, nested calculations, and automatic recalculation for everyday worksheet use.	Compared with WPS: Word formula features are centered on document tables, not a full spreadsheet editing environment.	Compared with WPS: Google Sheets emphasizes online collaboration and AI-assisted formula creation, while WPS fits local desktop spreadsheet editing more directly.	Compared with WPS: Notion formulas are database-property based, so the editing model differs from cell-by-cell spreadsheet formulas.	Compared with WPS: Acrobat focuses on PDF form calculations and does not provide a standard spreadsheet formula workflow.

Overall Conclusion
If your main task is entering formulas and calculating results in a Windows desktop spreadsheet, WPS ACOS fits that workflow closely. If your work is centered on document tables, online database-style collaboration, or PDF form calculations, Microsoft, Google, Notion, or Adobe may fit those specific scenarios better.

Use Cases

#	Scenario	Target Users	Core Pain Point	Solution
1	Trigonometric calculations	Students, teachers	Need to return an inverse cosine result quickly	Enter `=ACOS(value)` in a cell
2	Data analysis models	Data workers	Need to include inverse cosine in a formula chain	Combine ACOS with other nested functions
3	Cross-worksheet calculations	Finance and operations staff	Data is spread across different worksheets	Reference cells from other worksheets inside ACOS
4	Dynamic result updates	Everyday office users	Results need to update after source data changes	Use automatic recalculation to keep results in sync
5	Formula learning and demos	Trainers and beginners	Not familiar with function parameters	Use syntax guidance while entering the formula
