Returns the tangent of a complex number.
IMTAN( Z )
- where z is a complex number as described in Documentation/How_Tos/Calc:_Complex_Number_functions
IMTAN( Z ) is equivalent to
IMDIV(IMSIN( z );IMCOS( 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
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.
