IMTAN function

PRO BASIC

The IMTAN function in Jspreadsheet Formulas Pro is used to calculate the tangent of a complex number. A complex number is a value composed of a real and an imaginary part, and this function allows you to find its tangent, a mathematical concept often used in complex number calculations and engineering applications. With IMTAN, you provide a complex number as input, and the function returns its tangent in complex form. It's a helpful tool for managing complex mathematical operations in Jspreadsheet.

Documentation

Returns the tangent of a complex number.

Syntax

IMTAN(inumber)

Parameter	Description
`inumber`	The complex number for which you want to calculate the tangent.

Behavior

The IMTAN function returns the tangent of a specified complex number. The function takes the form IMTAN(inumber), where inumber is the complex number for which you want to calculate the tangent.

If inumber is a blank or empty cell, IMTAN will return a #NUM! error.
If inumber is a text string that cannot be interpreted as a complex number, IMTAN will return a #VALUE! error.
If inumber is a boolean value (TRUE or FALSE), it will be coerced to a number (1 or 0 respectively) and processed as such.
If inumber contains a reference to a cell with an error, IMTAN will propagate that error.
The result of IMTAN is a complex number expressed in the form x + yi or x + yj.

Common Errors

Error	Description
#NUM!	Occurs if the `inumber` argument is an empty cell.
#VALUE!	Occurs if the `inumber` argument is a text string that cannot be interpreted as a complex number.
#REF!	Occurs if the `inumber` argument contains an invalid or missing cell reference.

Best practices

Always ensure that the inumber argument is a valid complex number or a reference to a cell containing a valid complex number.

Be aware that IMTAN will interpret boolean values as numbers, which might not be the desired behavior.

Use error handling functions like IFERROR or ISERROR to catch possible errors in the inumber argument.

Keep in mind that the result of IMTAN is a complex number, so ensure your spreadsheet or further calculations can handle this type of result.

Usage

A few examples using the IMTAN function.

IMTAN("1+i") returns 0.271752585319512+1.08392332733869i
IMTAN("0+2i") returns 0.964027580075817i
IMTAN("3") returns -0.142546543074278
