Overview
Calculates the inverse hyperbolic cosine of the pixels in a raster.
Notes
In mathematics, all trigonometric functions have a defined range of valid input values, called the domain. The output values from each function also have a defined range. For this tool, the domain and range are as follows:
 Domain: 1 ≤ [in_value] < ∞ Note that any input value that is outside this domain will receive NoData on the output raster.
 Range: ∞ < [out_value] < ∞
The input values to this tool are interpreted as unitless.
The output raster is always a floatingpoint type, regardless of the input value type.
Parameters
Parameter name  Description 

Raster  The input for which to calculate the inverse hyperbolic cosine values. 
Extent Type  Choose which extent should be used in the output raster:

Cellsize Type  Choose which cell size to use in the output raster. If all the input cell sizes are the same, all the options will yield the same results.
