Use wct.IMCOS to return the cosine of a complex number in x + yi or x + yj text format.
Syntax
SELECT [wctEngineering].[wct].[IMCOS] (
<@inumber, nvarchar(4000),>)
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 converted to float and yi (or yj) is an imaginary number, where the y part can be converted to float.
Return Types
varchar(4000)
Remarks
· Use COMPLEX to convert real and imaginary coefficients into a complex number
Examples
select wct.IMCOS('7+24i')
This produces the following result

9985104444.63206-8701499125.56623i
