ASINH

Purpose:

Calculates the inverse hyperbolic sine of any expression.

ASINH(val)

val

A scalar, series or table.

A scalar, series, or table.

asinh(-10..0.01..10);gridhv;griddot

$image\asinhpic01.gif$

displays the inverse hyperbolic sine from –10 to 10.

asinh(i)

returns 0 + 1.570796 i or (π/2)i.

asinh(-2..0.1..2)

returns a 41 point real series.

The inverse hyperbolic sine is defined as:

for all complex z. The function is multi-valued and this definition places the branch cut in the complex plane at [-i ∞, -i] and [i, i ∞].

SETDEGREE and SETRADIAN have no effect on this function because it always operates in radians.
