An overview of the Trigonometric Math toolset
Trigonometric Math tools perform various trigonometric calculations on the values in an input raster.
There are several general categories of trigonometric calculations. The available tools in each of the categories are listed here:
 Standard trigonometric tools:
 Cos (cosine), Sin (sine), Tan (tangent).
 Inverse (or "arc") trigonometric tools:
 ACos (inverse cosine), ASin (inverse sine), ATan (inverse tangent).
 There is also an inverse tangent based on x,y, as ATan2.
 ACos (inverse cosine), ASin (inverse sine), ATan (inverse tangent).
 Hyperbolic trigonometric tools:
 CosH (hyperbolic cosine), SinH (hyperbolic sine), TanH (hyperbolic tangent ).
 Inverse hyperbolic trigonometric tools:
 ACosH (inverse hyperbolic cosine), ASinH (inverse hyperbolic sine), ATanH (inverse hyperbolic tangent).
The following table lists the available Trigonometric Math tools and provides a brief description of each:
