IMCOS

IMCOS(inumber)

Returns the cosine of a complex number.

inumber

The complex number for which you want the cosine.

REMARKS

* If "inumber" is not in the form of x + yi or x + yj, then #NUM! is returned.
* If "inumber" is not text, then #VALUE! is returned.
* You can use the IMCOSH function to return the hyperbolic cosine of a complex number.
* You can use the IMSIN function to return the sine of a complex number.
* You can use the IMTAN function to return the tangent of a complex number.
* You can use the COMPLEX function to convert real and imaginary coefficients into a complex number.
