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.
