Code Sample

Tan example 1 (Python window)

This example calculates the tangent of the values in the input GRID raster.

import arcpy
from arcpy import env
from arcpy.sa import *
env.workspace = "C:/sapyexamples/data"
outTan = Tan("degs")
outTan.save("C:/sapyexamples/output/outtan")
Tan example 2 (stand-alone script)

This example calculates the tangent of the values in the input GRID raster and outputs a TIFF raster.
