Syntax

SELECT [westclintech].[wct].[IMSIN] (
   <@inumber, nvarchar(4000),>)

Description

Use the scalar function IMSIN to return the sine of a complex number in x + yi or x + yj text format. The sine of a complex number is computed by:

\sin(x+yi)=\sin(x)\cosh(y)+\cos(x)\cosh(y)i

Arguments

@inumber

is the value at which to evaluate the function. @inumber is an expression of type varchar or of a type that can be implicitly converted to varchar and must be in the format x + yi or x + yj, where x is a real number that can be converted to float and yi (or yj) is an imaginary number, where the y part can be converted to float.

Return Type

nvarchar(4000)

Remarks

Use COMPLEX to convert real and imaginary coefficients into a complex number

Examples

select wct.IMSIN('7+24i');

This produces the following result.

{"columns":[{"field":"column 1"}],"rows":[{"column 1":"8701499125.56623+9985104444.63206i"}]}
