Calculates the inverse 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 have a defined range. For this tool, the following are true:
The Domain is: -1 ≤ [in_value] ≤ 1
Note that any input value that is outside this domain will receive NoData on the output raster.
The Range is: -pi/2 ≤ [out_value] ≤ pi/2
The input values to this tool are interpreted as unitless.
Output values are always floating point, regardless of the input data type.
The output values from this tool are in radians. To use degrees instead, the resulting raster must be multiplied by the radians-to-degrees conversion factor of 180/pi, or approximately 57.296.
For further assistance, a procedure to follow and examples of converting output in radians to degrees are available.
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.
If the input is multidimensional raster data, all slices from all variables will be processed. The output will be a multidimensional raster in CRF format.
