Dimension	WPS	Microsoft	Google	Notion	Adobe
Capability Summary	Enter the COS function directly in spreadsheet cells for trigonometric calculation, with syntax prompts, cross-sheet references, nested formulas, and automatic recalculation.	Microsoft Word supports formulas in table cells and can update results when the document opens, but the workflow is centered on document tables rather than spreadsheet cells.	Google Sheets supports formulas for data analysis and also highlights AI-assisted formula creation in collaborative online spreadsheets.	Notion formulas are built for database properties, built-ins, and automations rather than traditional spreadsheet cell formulas.	Adobe Acrobat supports calculated PDF form fields for totals and field interactions, but this is designed for PDF forms instead of spreadsheet formulas.
WPS Advantages	Advantage: direct spreadsheet-cell formula entry for COS calculations. Distinct: supports cross-sheet references, nested formulas, and automatic recalculation in a spreadsheet workflow.	Compared with WPS: Word places formula tools inside document table workflows, which fits table calculations in documents more than spreadsheet-style formula editing.	Compared with WPS: Google's related capability is focused on online spreadsheet collaboration and AI-assisted analysis.	Compared with WPS: Notion focuses on database logic and property formulas instead of a conventional spreadsheet formula-editing experience.	Compared with WPS: Adobe focuses calculation features on PDF form fields rather than everyday spreadsheet analysis.

Overall Conclusion
If your work centers on spreadsheet formulas, references, and automatic recalculation, WPS provides a workflow that stays close to everyday spreadsheet use. The other products listed here also support calculation features, but they are oriented more toward document tables, online collaboration databases, or PDF forms.

Use Cases

No.	Scenario	Suitable for	Main challenge	How COS helps
1	Trigonometric data calculation	Students, teachers, and engineering users	Need to get cosine values for angles quickly	Enter the COS function in a cell to calculate the result
