IMTAN function

The IMTAN function returns the tangent of the given complex number. For example, a given complex number "x+yi" returns "tan(x+yi)."

Parts of an IMTAN formula

IMTAN(number)

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

IMTAN(COMPLEX(4, 6))

IMTAN(4)

IMTAN("2+3i")

Notes

The IMTAN function returns an error if the given number isn’t a valid complex number or if the tangent function is undefined for the given number.
