Calculates the sine of cells in a raster.
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] ≤ 1
Note that here -∞ and ∞ represent the smallest negative and largest positive value supported by the particular raster format, respectively.
The input values for this tool are interpreted to be in radians. If the input you wish to use is in degrees, the values must first be divided by the radians-to-degrees conversion factor of 180/pi, or approximately 57.296.
For further assistance, a procedure to follow and some examples of converting input values in degrees to radians are available.
The output values from this tool are interpreted as unitless.
Output values are always floating point, regardless of the input data type.
Due to the range of values, applying a linear stretch renderer can be useful to better see the results.
See Analysis environments and Spatial Analyst for additional details on the geoprocessing environments that apply to this tool.
The input for which to calculate the sine 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|
The output raster.
The values are the sine of the input values.
Sin example 1 (Python window)
This example calculates the sine of the values in the input Grid raster.
import arcpy from arcpy import env from arcpy.sa import * env.workspace = "C:/sapyexamples/data" outSin = Sin("degs") outSin.save("C:/sapyexamples/output/outsin")
Sin example 2 (stand-alone script)
This example calculates the sine of the values in the input Grid raster and outputs an IMG raster.
