How To Use TAN function in Excel Explained

The TAN function in Excel calculates the tangent of an angle in radians. It is used to find the slope or tilt of an object and for various mathematical and engineering applications.

The TAN function in Excel is used to calculate the tangent of a given angle. It takes a single argument, the angle in radians, and returns the tangent of that angle. The function is part of the Math & Trig group of functions.

The function can be used in a variety of calculations, such as finding the angle of a triangle or the length of a side. It can also be used to calculate angles in trigonometry or in graphics applications.

To use the function in Excel, enter the angle in radians in a cell and then use the formula =Tan(angle). The result will be the tangent of the angle.

For example, if you want to find the tangent of an angle of 30 degrees, the formula would be =Tan(30*PI()/180). The result is 0.57735026919.

The function can also convert an angle in degrees to radians by multiplying the angle in degrees by PI()/180. For example, if you want to convert 45 degrees to radians, the formula would be =Tan(45*PI()/180), which will return the result 0.78539816339. 

=TAN(number)

1. Open your Microsoft Excel workbook.
2. Enter the data in the appropriate cells, making sure to include the angle that you want to apply the tan formula to.
3. Select the cell you would like the function to be applied.
4. Click on the “Formulas” tab at the top of the screen. Select the “Math & Trig” option from the list of dropdown options. Select the “Tan” option from the list of functions.
5. Enter the cell reference of the angle you would like to apply the tan formula to in the “Number” field.
6. Click “OK” and the function will be applied to the angle in the specified cell.
