IMCOSH
Returns the hyperbolic cosine of a complex number.
Syntax
IMCOSH( z )
- where z is a complex number as described in Documentation/How_Tos/Calc:_Complex_Number_functions
Sematics
IMCOSH("a+bj") calculates
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
IMCOT( z )
- where z is a complex number as described in Documentation/How_Tos/Calc:_Complex_Number_functions
Semantics
IMCOT( z ) is equivalent to IMDIV(IMCOS(z);IMSIN(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.
IMCSC
Returns the cosecant of a complex number.
Syntax
IMCSC( z )
- where z is a complex number as described in Documentation/How_Tos/Calc:_Complex_Number_functions
Semantics
IMCSC( z ) is equivalent to IMDIV(1;IMSIN( 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.
IMCSCH
Returns the hyperbolic cosecant of a complex number.
