Summary:

Sc func imsec.png

Syntax:

IMSEC(Complex_number)

Returns:

The result is presented in the string format and has the character "i" or "j" as an imaginary unit.

The function always returns a string representing a complex number. If the result is a complex number with one of its parts (a or b) equal to zero, that part is not displayed.

Arguments:

Complex_number is a complex number whose secant needs to be calculated.

A complex number is a string expression resulting in the form "a+bi" or "a+bj", where a and b are numbers. If the complex number is actually a real number (b=0), then it can be either a string expression or a number value.

Additional details:

Examples:

=IMSEC("4-3i") returns -0.0652940278579471+0.0752249603027732i.

=IMSEC(2) returns -2.40299796172238 as a string. The imaginary part is equal to zero, so it is not displayed in the result.
