IMSECH

Returns the hyperbolic secant of a complex number.

Syntax

IMSECH( z )

where z is a complex number as described in Documentation/How_Tos/Calc:_Complex_Number_functions

Semantics

IMSECH( z ) is equivalent to IMDIV(1;IMCOSH( z )).

To get better accuracy it is not implemented that way. With the notation IMCOT("a+bj")="c+dj" the used formulas are

real part

imaginary part

Issues

The function is not implemented in versions before AOO 4.0 and before LibO 3.7.
