This is a new function introduced in Excel 2013. This is one of the important functions available in Excel 2013. This function is in the category of "Math and Trigonometry". This function is used to return the hyperbolic secant of an angle. The syntax of this function is as follows: =sech(number) where number is the angle of which we want to return a hyperbolic secant using the sech function available in Excel 2013. For example =sech(30) returns the hyperbolic secant of 30 .i.e. 6.482921235.
Let's have a look at the following.
First go to Excel 2013.
Now select a blank Excel workbook template from the available templates.
Now write the following number of which we want to determine the hyperbolic secant value.
Now write the following function.
The output is as follows:
