GET Tangent Value using TAN Function in Excel

The TAN function in Excel calculates and returns the Tangent of a given radians.

Trigonometric Function in ExcelTAN(θ) =  Opposite / Adjacent     = a/b

Tan of the angle θ, is the ratio of the opposite side – a, to the adjacent side – b.

 

Syntax of TAN Function in Excel

TAN(number)

Where Argument number is angle in radians which you need to calculate the tangent of.

NOTE: If your angle is in degrees, you will need to convert it into radians before supplying it to the TAN Function with the help of Radians function

=RADIANS( degrees )

 

Example of TAN Function in Excel
