About This Feature

Overview

The COS function in WPS Spreadsheet returns the cosine of a number with the syntax COS(number). For users searching how to use the COS function in WPS on Windows, the main workflows are inserting the function from the dialog box, typing the formula directly in a cell, and checking syntax or parameter help when needed.

Core tasks include:

  • Insert COS from the Insert Function dialog when you want a guided function entry flow.
  • Type =COS(...) directly in a cell or in the formula bar for faster spreadsheet work.
  • Review syntax and parameter help before or during formula entry.

This WPS Office formula workflow is suitable for trigonometric calculations, spreadsheet formula entry, and checking function syntax before calculation.
