Summary
Calculates the hyperbolic cosine of cells in a raster.
Illustration
Usage
In mathematics, all Trigonometric functions have a defined range of valid input values, called the domain. The output values from each function also has a defined range. For this tool
The Domain is : -∞ < [in_value] < ∞
The Range is : 1 ≤ [out_value] < ∞
Note that here -∞ and ∞ represent the smallest negative and largest positive value supported by the particular raster format, respectively.
The input and output values for this tool are interpreted as unitless.
Output values are always floating point, regardless of the input data type.
See Analysis environments and Spatial Analyst for additional details on the geoprocessing environments that apply to this tool.
Syntax
CosH (in_raster_or_constant)
| Parameter | Explanation | Data Type |
in_raster_or_constant | The input for which to calculate the hyperbolic cosine values. In order to use a number as an input for this parameter, the cell size and extent must first be set in the environment. | Raster Layer | Constant |
Return Value
| Name | Explanation | Data Type |
| out_raster | The output raster. The values are the hyperbolic cosine of the input values. | Raster |
Code sample
CosH example 1 (Python window)
This example calculates the hyperbolic cosine of the values in the input Grid raster.
import arcpy
from arcpy import env
from arcpy.sa import *
env.workspace = "C:/sapyexamples/data"
outCosH = CosH("degs")
outCosH.save("C:/sapyexamples/output/outcosh")
CosH example 2 (stand-alone script)
This example calculates the hyperbolic cosine of the values in the input Grid raster and outputs an IMG raster.
