FynW6‖Returns the tangent of a complex number. The tangent of a complex number can be expressed by:
7XNKJ‖        
7QtEG‖IMTAN(Complex_number)
4XwP7‖Complex_number is a complex number whose tangent is 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.
	
bEY6r‖=IMTAN("4-3i")
returns 0.00490825806749606-1.00070953606723i.
q7Zeh‖=IMTAN(2)
returns -2.18503986326152 as a string. The imaginary part is equal to zero, so it is not displayed in the result.
