## Trigonometry Functions in Excel:

This page shows the **list of built-in Excel Trigonometry Functions in Office 365.**

If you are curious to learn the functions of SIN, COS, TAN, and even more, you can easily find them in the Excel Trigonometry Functions. In addition, Excel offers functions for converting angles between radians and degrees.

Click on a function name or read more columns in order to know the complete description of the function with examples.

**Note:** Excel version is specified in some functions that indicate the introduction of that particular function in Excel. For example, 2013 indicates that the function will be available in Excel 2013 and all the newest versions.
