I used to have a HP41C, and bought a book from a company in Orgeon. It was written like with cartoons, and verrry easy to understand. Does anyone remember this company, and do they still exist? The book was in a spiral bound format. Thanks

How do you exchange rect to polar and back? just change modes? --- On Thu, 7/31/08, Fatih Can <f_can2003@...> wrote:

I have to do this a lot, and on the 48 it was simple. On the 50g it isn t. The options are to change modes, or to install the Keyman and OT49+ libraries and

In case you've had trouble finding the menu and assuming the 50 is the same as the 49, you can try...
PRG -> NXT -> MODES -> ANGLE
With the coordinate on the stack, pressing RECT or CYLIN will make switch accordingly.

That's just one way of doing it. You can read up on CUSTOM menus for another way to customize your hp50.
Have fun. :)

Wow! I didn't get any of that...sorry. I can switch modes (rectangular, polar, spherical); is there a way to CONVERT polar coordinates to rectangular - quick and easy? (i.e. theta = pi over 3 to (x,y) push a button(or two) and bingo!) Do I have to upload something to my 50g to do it? Thanks, Scott
2008-08-10 by Don Hart
You can get to the commands that do that by pressing, in order, PRG -> NXT -> MODES -> ANGLE Then, with the coordinate on the stack, press RECT or CYLIN will make switch accordingly. This will convert ALL coodinates on the stack no matter what level they're on. You don't have to do anything special other than navigate to the commands. You can also assign those commands to almost any key on the keyboard as outlined in message #487. Then they'll be directly accessible without any such navigation. Does that clear it up? If not, please post a question more spacific as to where you're having a problem. --- On Sun, 8/10/08, ramwriter3k <attkbeast@...> wrote:

If your calculator is in rectangular mode. You can enter a complex number in polar form : ( r alpha right-shift 6 theta enter , and it will be immediately converted. _____

Does anyone know how to switch function between polar to rectangular and rectangular to polar using the softkeys or a better way then going into mode and changing it this way? Also is there a softkey or shortcut for the angle symbol(polar),such as the one on the hp 48? Thnak you Tony

I spent the last week and a half reading 1000 pages of broken, illiterate nonsense. Everything is trial and error with the HP50G. I've owned the calculator for over two years and the idiots at HP still can't hire a 9th grader to write a useful manual for them. The only way I've found to convert from polar to rectangular and vise versa is to write a program which will appear on a soft key in the directory you choose. I just started trying to figure out how to program, but programming is twice as ridiculous as figuring out the conversion. The commands for inputing a variable are two lines long and make no sense. Then the variable has to be purged afterwards... Absolutely idiotic...

There are different ways to toggle the polar mode. You can assign a program like... << IF -16 FS? THEN -16 CF ELSE -16 SF END >> ...to a little used key Or you can put it into a custom (CST) menu, which is what I did. Since it sounds like you're a former 48 user, I've attached a custom menu I wrote when I first got my 49 -- should work on a 50. It made my transition from the 48 easier. Rename it to CST and store it in the HOME directory. Press CUSTOM on the keyboard to use it. The polar toggle is under the TOGGLE soft key. Modify as you see fit. The angle symbol is at [ALPHA] [RIGHT-SHIFT] 6 --- On Wed, 6/10/09, tony <anthonypicariello@...> wrote:

If you use local variables, you don't have to purge them. They're never stored (STO). Or you can PURGE the stored vars in your program right before it ends. And you don't have to use the INFORM or INPUT for getting input in the middle of a program. You can put a prompting string on the stack and use the HALT command. The following example illustrates this. After entering a number in response to the prompt, you then press the CONT key. << 2 3 * "enter a number" HALT SWAP DROP 4 * *>> or << 2 3 * "enter a number" HALT SWAP DROP DUP 'X' STO 4 * *>> ...if you want to store it. --- On Wed, 6/10/09, rickwendel763242 <rickwendel763242@...> wrote:

They recommend to learn to use the hp 50g by reading the manuals of the hp 48 or hp 49, I have learned some things by reading the hp 48 manual. There is also the advanced user guide for the hp 49 which is very useful.
