IMSEC function
Returns the secant of a complex number. The secant of a complex number can be expressed by:
This function is part of the Open Document Format for Office Applications (OpenDocument) standard Version 1.2. (ISO/IEC 26300:2-2015)
IMSEC(Complex_number)
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.
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.
=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.
