About This Feature

Overview

SECH is a built-in function in WPS Office AirSheet on Windows that returns the hyperbolic secant of a given number. It fits spreadsheet work such as math practice, engineering calculations, and formula-based analysis.

Core capabilities include:

Enter =SECH(number) directly in a cell to calculate a result.
View syntax prompts while typing the function name.
Use the function with cell references and nested formulas.
Update results automatically when referenced data changes.

System Requirements

Item	Requirement
OS	A Windows device that can run WPS Office
App version	It is recommended to use the latest version of WPS Office
Network	Local function calculation does not require a network connection; download, installation, and account services do require network access
Other	You need to open WPS AirSheet and edit worksheet cells

Download & Installation

Capability Summary	In WPS AirSheet, you can enter `=SECH(` in a cell and use syntax prompts, cell references, nested formulas, and automatic recalculation.	Excel provides the `SECH(number)` function and documents its syntax, argument limits, and error values.	The official Google Docs page focuses on document writing and Gemini assistance, and does not describe a SECH spreadsheet function.	Notion supports math equations through KaTeX and LaTeX-style input for displaying formulas, rather than spreadsheet function calculation.	Acrobat Desktop Help focuses on PDF creation, editing, and conversion workflows, not spreadsheet functions such as SECH.
WPS Advantages	Advantage: You can enter and recalculate the function directly in spreadsheet cells for ongoing worksheet calculations. Advantage: The source content shows no membership restriction for using this function.	Compared with WPS: Excel offers the same function name, while the official page focuses more on syntax rules and constraints than on in-cell guidance during entry.	Compared with WPS: The official page is centered on document authoring rather than spreadsheet function workflows.	Compared with WPS: Notion is better suited to equation display and note-taking than cell-based function calculation.	Compared with WPS: Acrobat is designed for PDF workflows and does not provide a comparable spreadsheet function entry experience.

Overall Conclusion
WPS and Microsoft Excel both support spreadsheet-based SECH calculations for direct worksheet use. Google Docs, Notion, and Adobe Acrobat officially emphasize document, equation display, or PDF scenarios instead of spreadsheet function calculation.

Use Cases

#	Scenario	Target Users	Core Pain Point	Solution
1	Math function practice	Students, teachers	Need to verify hyperbolic function results quickly	Enter a SECH formula in a cell and review the result
2	Engineering parameter calculation	Engineers, researchers	Need to include a hyperbolic function in an existing formula chain	Combine SECH with other functions in nested formulas
3	Template-based data analysis	Finance and analysis users	Manual recalculation is inefficient when data changes	Use cell references so results update automatically
4	Formula teaching demos	Trainers and instructors	Need to explain parameters while entering a function	Use syntax prompts to show the function format
5	Cross-sheet calculation review	Office users	Referencing data across sheets can be error-prone	Reference other cells or worksheet data in the formula
