Excel IMSECH function
The IMSECH function returns the hyperbolic secant of a complex number in the form x + yi or x + yj.
Note: You can apply the COMPLEX function to convert real and imaginary coefficients to a complex number of the form x + yi or x + yj.
Syntax
IMSECH(inumber)
Arguments
- inumber (required): The complex number for which you want the hyperbolic secant.
Remarks
Return value
It returns a complex number as text.
Example
To calculate the hyperbolic secant of the complex numbers in the following table, you can do as follows.
Select a cell (say D6), enter the formula below and press the Enter key to get the hyperbolic secant of the first complex number. Select this result cell and then drag its AutoFill Handle down to get the rest of the results.
=IMSECH(B6)
