Calculates the tangent 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: -∞ < [in_value] < ∞
The Range is: -∞ < [out_value] < ∞
Note that -∞ and ∞ represent the smallest negative and largest positive values supported by the particular raster format, respectively.
The input values for this tool are interpreted to be in radians. If the input you want 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 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 Histogram Equalized stretch renderer can be useful to best see the results.
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.

Input raster or constant value | The input for which to calculate the tangent 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 |
