Returns the cotangent of a complex number.
Sample Usage
IMCOT(COMPLEX(4,1))
IMCOT(C5)
IMCOT("3+4i")
Syntax
IMCOT(complex_number)
- complex_number - The complex number whose cotangent is to be computed.
Examples
IMCOT(COMPLEX(4,1)) returns the cotangent of the complex number formed by the COMPLEX function.
IMCOT(C5) returns the cotangent of the complex number contained in C5.
Notes
- The IMCOT function returns an error if the given number is not a valid complex number.
- complex_number can be either the result of the COMPLEX function, or a real number (interpreted as a complex number with imaginary part equal to 0), or a string in the format “x+yi” where x and y are numeric.
