IMSECH
Returns the hyperbolic secant of a complex number.
Syntax
IMSECH( z )
- where z is a complex number as described in 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.
This function currently appears in the AddIn category of the Function Wizard.
