IMSIN functionThe 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
IMSIN(COMPLEX(4,6))
IMSIN(4)
IMSIN(“2+3i”)
Notes
The IMSIN function returns an error if the given number isn’t a valid complex number.
