Excerpt 

Computes the arcsine of an input value for a hyperbolic angle measured in radians. The value can be a Decimal or Integer literal or a reference to a column containing numeric values. 
A hyperbola is the shape created by taking a planar slice of two cones whose tips are touching each other. For two identical cones, the curves of the slices mirror each other, no matter the angle of the plane through the cones.
The hyperbolic arcsine (ASINH) function is computed using the following formula:
You can convert from degrees to radians. For more information, see RADIANS Function.
Numeric literal example:
D lang syntax 

RawWrangle  true 

Type  ref 

showNote  true 

WrangleText  derive type:single value: round(sinh(radians(30)),3) 


round(asinh(0.5),3) 
Output: Returns the computation of the hyperbolic angle in radians whose sine is 0.5
. The output value is rounded to three decimals: 0.481
.
Column reference example:

asinh(X) 
Output: Returns the hyperbolic angle the sine value for which is stored in radians in X
column.
