# Trigonometry

The Trigonometry functions offer trigonometric calculations for the values specified in them. The values are either numbers specified in the functions themselves, or are referenced through a spreadsheet cell.

Function Functions are tools that are available in Spreadsheet for processing and analyzing acquisitions or other results. You can add functions to your Spreadsheet job to create tool chains and produce results for specific applications. | Description
