# SinH (Spatial Analyst)

## Summary

Calculates the hyperbolic sine of cells in a raster.

## 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 following are true:

• The Domain is: -∞ < [in_value] < ∞

• The Range is: -∞ < [out_value] < ∞

Note that -∞ 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.

• If the input is a multiband raster, the output will be a multiband raster. The tool will perform the operation on each band in the input.

• In ArcPy, if the input is a multidimensional raster, all slices from all variables will be processed, and the output will be a multidimensional raster.

• See Analysis environments and Spatial Analyst for additional details on the geoprocessing environments that apply to this tool.

## Parameters

 Label Explanation Data Type Input raster or constant value The input for which to calculate the hyperbolic sine values.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

 Label Explanation Data Type Output raster The output raster.The values are the hyperbolic sine of the input values. Raster

`SinH(in_raster_or_constant)`
 Name Explanation Data Type in_raster_or_constant The input for which to calculate the hyperbolic sine values.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 sine of the input values. Raster

### Code sample

SinH example 1 (Python window)

This example calculates the hyperbolic sine of the values in the input Grid raster.

``````import arcpy
from arcpy import env
from arcpy.sa import *
env.workspace = "C:/sapyexamples/data"
outSinH = SinH("degs")
outSinH.save("C:/sapyexamples/output/outsinh")``````
SinH example 2 (stand-alone script)

This example calculates the hyperbolic sine of the values in the input Grid raster and outputs a TIFF raster.

``````# Name: SinH_Ex_02.py
# Description: Calculates the hyperbolic sine of cells in a raster
# Requirements: Spatial Analyst Extension

# Import system modules
import arcpy
from arcpy import env
from arcpy.sa import *

# Set environment settings
env.workspace = "C:/sapyexamples/data"

# Set local variables
inRaster = "degs"

# Execute SinH
outSinH = SinH(inRaster)

# Save the output
outSinH.save("C:/sapyexamples/output/outsinh.tif")``````
