**Part 1: Introduce**

๐ **Definition** The DEGREES function in Microsoft Excel is designed to convert radians into degrees.

๐ **Purpose** The primary Purpose of the DEGREES function is to facilitate the conversion of angle measurements from radians to degrees, commonly required in various mathematical and engineering calculations.

๐ **Syntax & Arguments**

`DEGREES(angle)`

**Angle**: This is the required argument. It represents the angle in radians that you wish to convert.

๐ **Explain the Arguments in the function**

**Angle**: The angle you input should be in radians. The function will then convert this radian value into its equivalent degree measurement.

๐ **Return value** The DEGREES function returns the converted value in degrees.

๐ **Remarks** Always ensure that the input value is in radians to get the correct conversion to degrees.
