Description

The Imatanh(z) function returns the inverse hyperbolic tangent of complex input z. Values returned are in radians, degree or gradian, depending on the setting of system.math.angularunits object property (which can also be set in the Options dialog box opened from menu Preference: Options.).

Syntax

complex atanh(complex z)

Parameter

z

can be any complex number.

Return

Returns inverse of hyperbolic tangent of complex z.

Example

complex vv=3+4i;
Imatanh(vv)=;
Imatanh(vv)=0.11750090731143+1.4099210495966i;
