==IMCOSH==
 
−
Returns the hyperbolic cosine of a complex number.
 
−
 
−
===Syntax===
 
−
<code>IMCOSH( z )</code>
 
−
: where z is a complex number as described in [[Documentation/How_Tos/Calc:_Complex_Number_functions]]
 
−
 
−
===Sematics===
 
−
: <code>IMCOSH("a+bj")</code> calculates:
 
−
: <math> \cosh{(a)}\, \cos{(b)}+ \sinh{(a)}\, \sin{(b)} \mbox{ j}  </math> 
 
−
 
−
===Issues===
 
−
The function is not implemented in versions before AOO 4.0 and before LibO 3.7.

−
==IMCOT==
 
−
Returns the cotangent of a complex number
 
−
 
−
===Syntax===
 
−
<code>IMCOT( z )</code>
 
−
: where z is a complex number as described in [[Documentation/How_Tos/Calc:_Complex_Number_functions]]
 
−
 
−
===Semantics===
 
−
: <code>IMCOT( z )</code> is equivalent to <code>IMDIV(IMCOS(z);IMSIN(z))</code>
 
−
: To get better accuracy it is not implemented that way. With the notation <code>IMCOT("a+bj")="c+dj"</code> the used formulas are
 
−
: <math> c =\sin(2a) \frac {1} {\cosh(2b)-\cos(2a)}</math> and <math>d=-\sinh(2b)  \frac {1} {\cosh(2b)-\cos(2a)}</math>
