Calculate the hyperbolic secant of a complex number.

`IMSECH(number)`

- inumber - a complex number required to calculate the hyperbolic secant

`=IMSEC("4+3i")`

The function is used to calculate the secant of a complex number. The syntax of the function is: =IMSEC(complex_number) where complex_number is the complex number for which you want to calculate the secant. For example, if you wanted to calculate the secant of the complex number 4+3i, you would use the above formula which would return -0.0652940278579471-0.0752249603027732i.

`=IMSEC("3i")`

The function can also be used to calculate the secant of an imaginary number. For example, if you wanted to calculate the secant of the imaginary number 3i, you would use this formula which would return 0.1542514498875840-1.000758964576850i.

`=IMSEC(4)`

The function can also be used to calculate the secant of a real number. For example, if you wanted to calculate the secant of the real number 4, you would use the above formula which would return 0.9092974268256817.

IMSECH is a function that calculates the hyperbolic secant of a complex number, taking the complex number as its argument.

- The IMSECH function calculates the hyperbolic secant of a complex number, given as an argument in x+yi or x+yj text format.

The IMSECH function is a mathematical function that calculates the hyperbolic secant of a complex number.

A complex number should be formatted as x + yi or x + yj, where x and y are real numbers.

If you use a logical value as the argument to IMSECH, the function will return #VALUE!
