Engineering - IMTAN Function
Description
The IMTAN function returns the tangent of a complex number in x + yi or x + yj text format. The tangent of a complex number is calculated by the following formula −
tan(z) = sin(z) / cos(z)
Syntax
IMTAN (inumber)
Arguments
| Argument | Description | Required/ Optional |
|---|---|---|
| Inumber | A complex number for which you want the tangent. | Required |
Notes
Complex Numbers in Excel are simply stored as text.
When a text string in the format "a + bi" or "a + bj" is supplied to one of Excel's built-in Complex Number Functions, this is interpreted as a complex number.
The complex number functions can accept a simple numeric value, as this is equivalent to a complex number whose imaginary coefficient is equal to 0.
Use COMPLEX to convert real and imaginary coefficients into a Complex Number.
If Inumber is not recognized as a complex number, IMTAN returns the #NUM! error.
If Inumber is a logical value, IMTAN returns the #VALUE! Error.
Applicability
Excel 2013, Excel 2016
