How to Use the ATAN Function in Excel
Below is a detailed guide on how to use the ATAN function in Microsoft Excel and Google Sheets.
Introduction
The ATAN function in Excel and Google Sheets is used to compute the arctangent of a number. It returns the arctangent value of a number in radians, within the range of -π/2 to π/2.
Syntax
The syntax for the ATAN function is consistent across both Excel and Google Sheets:
ATAN(number)number: The number whose arctangent value you wish to determine.
Examples
To further clarify the ATAN function, here are some practical examples:
| Number | ATAN(Number) |
|---|---|
| 1 | =ATAN(1) |
| 0 | =ATAN(0) |
| -1 | =ATAN(-1) |
Use Cases
The ATAN function has multiple applications, such as:
- Calculating Angles: It’s useful for deriving angles in right triangles, where the lengths of the opposite and adjacent sides are known.
- Engineering Calculations: Arctangent calculations are frequently employed in engineering to determine necessary angles for construction and design.
Implementation
Implementing the ATAN function in Excel and Google Sheets is straightforward:
Excel
In Excel, simply input the formula =ATAN(number) into a cell to compute the arctangent of the specified number.
Google Sheets
In Google Sheets, the procedure is identical. Enter the formula =ATAN(number) into a cell to obtain the arctangent value.
This concludes the comprehensive guide on utilizing the ATAN function in both Microsoft Excel and Google Sheets.
