WorksheetFunction.ImCos (Excel)
Returns the cosine of a complex number in x + yi or x + yj text format.
Use the Complex method to convert real and imaginary coefficients into a complex number. If inumber is a logical value, ImCos returns the #VALUE! error value. The cosine of a complex number is
ImCos (Arg1)
Arg1: Inumber - a complex number for which you want the cosine.
