That is hilarious reading that 14 years later. 2017 and I laughed when I read your comment.
FREE42 MANUAL SERIES
I found a mistake in HP 48G Series Advanced User's Reference Manual, Technical Reference, page F-8: The TRG* expansion for the function COS(x+y) is incorrectly written SAYS: COS(x)*COS(y)+SIN(x)*SIN(y). Can someone tell me where to get a copy of HP42s user guide, preferable in.

FREE42 MANUAL HOW TO
b) Got the Free42 simulator and want to know how to use it. I've been using Thomas Okken's Free42 on my PDA device and is looking for. I tried COS(x+y) expansion with TRG* and found the result is COS(x)*COS(y)-SIN(x)*SIN(y). This manual will be of interest to people who: a) Have a HP-42S calculator and lost its manual. On Section 20 -Calculus and Symbolic Manipulation-, SubSection 5 -Rearranging Symbolic Expressions-, SubSubSection 2 -Manipulating Subexpressions- page 20-19, To algebraically rearrange a particular subexpression: “move the selection cursos to the top-level function for the subexpression you want to rearrange, press RULES then press the menu key for transformation you want”. It will hopefully be a great help as I can barely turn the thing on. Kindly divide them into chapterwise files.
The stack is now exactly as he said it would be, namely T=7, Z=6, Y=2, and X=2, with Z and T having been lost.18975223 09-04-00 14:16 HP 48G Series User's Guide.pdfĭownloading a 14mb file is very difficult. Press Roll-down 4 times to verify these contents.
Sorry to disagree, but everything said about the stack in the quote above is correct, as can be seen by simply doing what he says, for example:įill the stack with 9, 8, 7, 6 (so Z=9 and X=6) When the 48SX reworked the and functions, they forgot that clever little trick (to swallow extra presses quietly) and thus permanently annoyed lots of users, contributing greatly to the religious wars we see today. The 'Too few arguments' error was annoying when pressing too many times, but this model had a separate back arrow key, which was (correctly) quietly swallowed when pressed with an empty stack. In my earliest attempts at teaching myself RPL on my 28S (yes, I waited for the improved model) this was by far the most frustrating behavior. Of course these things are much easier to see looking backwards than forwards. I truly believe that if HP had made an exception, and treated while having an empty stack as a NOP, then RPL would have been accepted by a much larger percentage of the RPN faithful, and likely even embraced by many of them, battleship h/w design notwithstanding. I can't stand the error that shows when you press <= on a 28/48/49/50 with an empty stack, for example That author obviously hasn't understood RPN and either remains in this state still or is unable to edit his text. What is described in the part you quoted is simply wrong. It's just I don't understand what José Lauro Strapasson tries to tell me there. Last but not least: What is bad on the behavior of these calculators? Maybe I just got too much used to the way it works so that I don't see the point anymore. So either this one has also a "bad" feature or there was just a short time where it was different. Now if I look at my HP17Bii+ in RPN Mode, it seems exactly the same to me as it is in the other HP RPN's I had and have. The second point is: he mentioned there is a better way to do RPN and it was implemented in HP48/49. My HP12C has the same behavior and as far as I remember my original HP11C had the same. There is no copying, deleting and moving around as described in that documentation.

If I have a look at the DM42, which always shows the whole stack (what a manifesto to RPN ), the stack ist simply some sort of lifo stack. There are really things I don't understand.įirst of all: the described behavior of the stack xyzt according to i) - iv) is in my understanding completely different. This is a feature, a bad feature I think, of the HP RPN style used by the 42S (also in the 33S, 12C, etc but not in the HP48 or 49). So if you do 2 ENTER + you will have 4 as answer. Iv)The content just entered goes to line y and line x. Iii)The content of line x goes to line z. Ii) The content of line y goes to line t. I) The content of lines t and z are lost. b) Got the Free42 simulator and want to know how to use it. When you enter a number (say 2 ENTER) what happens is the following. This manual will be of interest to people who: a) Have a HP-42S calculator and lost its manual. But since the calculator’s display has only two lines just x and y lines are visible.
