			Complex Function Plot Using HP-28 

	y=exp(Mag (1/(1+s)))    where s is  (jw)  EE notation or
                 			  (0+i*w) HP notation
        So in order to plot this function we plot:
		'EXP(ABS(P))'
        where P is      
		'INV(1+i*w)'
	or any other complex function.
	The point is you have to use  (a+i*b) notation not (a,b) 

	I hope this is the answer to your questions. 
	I plot frequency response using this method on my HP-28C 
	and it is satisfactory. But it is a little bit slower.
