IMSIN function

The IMSIN function returns the sine of the given complex number. For example, a given complex number "x+yi" returns "sin(x+yi)."

Parts of an IMSIN function

IMSIN (number)

Part Description Notes
number The complex number for which you want the sine.

This can be either the result of the COMPLEX function, a real number (which will be 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. 


Sample formulas
