TIME

Returns the secant of a complex number. The secant of a complex number can be expressed by:

sec(a+bi)=1/cos(a+bi)

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

བརྡ་སྤྲོད།

IMSIN(Complex number)

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

ཟུར་མཆན་རིས་རྟགས་

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.


ཐ་ཚིག་རིས་རྟགས་

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.


དཔེ་གཞི།

=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.
