Syntax

SELECT [westclintech].[wct].[COTH] (
   <@Z, float,>)

Use the scalar function COTH to calculate the hyperbolic cotangent of a hyperbolic angle.

The number of interest. @Z must be of type float or of a type that implicitly converts to float.

float

COTH is undefined at 0.

Example #1

SELECT wct.COTH(2) as COTH;

This produces the following result.

{"columns":[{"field":"COTH","headerClass":"ag-right-aligned-header","cellClass":"ag-right-aligned-cell"}],"rows":[{"COTH":"1.03731472072755"}]}

Example #2

The following SQL can be run and the results pasted into Excel to graph the results of the function in the range -10, 10.

SELECT SeriesValue as z,

       wct.COTH(Seriesvalue) as COTH

FROM wct.SERIESFLOAT(-10, 10, .01, NULL, NULL);

Here's the graph of the results
