Re: Im looking for a HP RPN calculator, which one is good to get? Message #7 Posted by Ellis Easley on 27 Oct 2002, 1:21 p.m., in response to message #3 by K.C.
K.C. said:
"Its hard to enter long equations and work with numbers on my HP30S and Im looking for something more efficient."
If K.C. wants to be able to enter complete equations into the calculator, wouldn't that limit the choice of HP's to those with a memory stack and algebraic capability like the 28C/S, 48S/SX/G/GX (/GX+? or /G+?), 38G, 39G or 49G? Entering an equation in RPN is a matter of evaluating it numerically stepbystep, in a more efficient way than the "Algebraic Entry" systems.
I know the 28C/S can be programmed to display graphics, but isn't it true that they don't have graphing functions (other than primitive bitmap operations) builtin? If so, and if K.C. wants both RPN and symbolic equation capability, in a machine without graphics capability, the 28C or 28S would be the choices.
