Returns the hyperbolic secant of a complex number. The hyperbolic secant of a complex number can be expressed by:

IMSECH equation

The result is presented in the string format and has the character "i" or "j" as an imaginary unit.

If the result is a complex number with one of its parts (a or b) equal to zero, that part is not displayed.


returns -0.0362534969158689+0.00516434460775318i.

returns 0.26580222883408 as a string. The imaginary part is equal to zero, so it is not displayed in the result.
