About This Feature
Overview
The SEC function in WPS Spreadsheet returns the secant value for a given angle in radians. It is useful for trigonometric calculations, formula checks, and repeated calculations across worksheet ranges.
Core tasks in this guide include:
- Insert the SEC function from the Insert Function dialog.
- Type
=SEC(...)directly in a cell or in the formula bar. - Review the
SEC(number)syntax and parameter description before applying the formula.

Compare with Alternatives
| Dimension | WPS | Microsoft | Notion | Adobe | |
|---|---|---|---|---|---|
| Capability Summary | WPS Spreadsheet supports the SEC function and lets you use it through Insert Function, direct formula entry, and function help. | Microsoft Excel provides the SEC function and describes its required argument as an angle in radians. | Google Docs officially supports inserting equations and symbols in documents, but the cited page does not describe a spreadsheet SEC function workflow. | Notion formulas support properties, operators, and functions for database calculations rather than a worksheet-style SEC function workflow. | Adobe Acrobat supports calculation rules for PDF form fields, which fits form workflows rather than spreadsheet trigonometric formulas. |
| WPS Advantages | Advantage: WPS matches the worksheet cell calculation workflow directly. Distinct: it supports both dialog-based insertion and direct formula entry for the same function. | Compared with WPS: Excel also provides a SEC function, so the calculation scenario is similar. | Compared with WPS: the official page focuses on document equation editing instead of worksheet function entry. | Compared with WPS: the formula model is centered on database properties, not spreadsheet cells with SEC syntax. | Compared with WPS: the calculation workflow is designed for PDF forms instead of spreadsheet trigonometric formulas. |
| Official Source | — | SEC function | Use equations in a document | Formula syntax and functions | Configure form field calculations in Acrobat |
Overall Conclusion: For worksheet-based trigonometric calculations on Windows, WPS keeps the SEC workflow close to everyday spreadsheet editing. The other products in this comparison focus on adjacent scenarios such as document equations, database formulas, or PDF form calculations.
Use Cases
| No. | Scenario | Suitable for | Main need | How SEC helps |
|---|---|---|---|---|
| 1 | Trigonometric calculation | Students and teachers | Get a secant result quickly | Enter =SEC(...) in a worksheet cell |
| 2 | Formula entry checking | Analysts and office users | Confirm the parameter format before calculation | Use Insert Function to review the parameter input area |
| 3 | Repeated worksheet processing | Office users | Apply the same calculation to multiple cells | Enter the formula once and fill it down |
| 4 | Syntax learning | New users | Learn how the function is written | Review the SEC(number) syntax in function help |
| 5 | Result troubleshooting | Intermediate users | Check why a result looks incorrect | Review parameter type, angle format, and referenced cells |
