IMTAN

Returns the tangent of a complex number.

Syntax

IMTAN( Z )

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

Semantics

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

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.
