content: Hey All,Just got my HP 50G this morning, and I've been busily practising using it. I happened to notice that the CONJ function seems to only accept one type of argument;CONJ(25+50i)It doesn't seem to like;CONJ(25,50)CONJU(55<63.5)Am I just doing it wrong, or is this how it is on the big HP?Cheers,Peter

content: It should work fine. Do you have the complex mode turned on in the mode-cas menu?Also when working with polar coordinates, there has to be a comma before the angle symbol. Also, I am not sure what the CONJU command is.Richard.

content: Hi Richard,Ah, didn't realise that was the case. It doesn't seem to mind with simple arithmetic. I'll try that. Thanks!CONJU is a me trying to type the whole word... My bad!

content: The manual says to use a comma before the angle symbol in a complex number, but I just tried it on my 49G running 50G firmware, and it was fine with or without the comma.Looks like either format is fine.Richard.

content: Ah, just twigged...CONJ ((23<45)) works nicely. Thanks guys!

content: Hello, I wonder why myHP 50gemulatorcannot computeATAN(2+sqrt(3)).Any idea? Is it just an emulator bug or what?Can someone try it with a real HP 50g?My rather cheap Casio calculators have no problem at all.

content: HP Prime gets the symbolic answer in CAS mode and the numeric answer otherwise. HP 48 GX gets the right numeric answer.

content: On a physical 50G, you first have to chose Algebraic mode, instead of RPN.Usually, it's also in the non-numeric mode, i.e. it displays results in a symbolic way.Then you may enter this term like displayed., and the display looks exactly like your emulator, after pressing ENTER.Afterwards, the numerical value (1.308...) is displayed only after hitting ->NUM and ENTERIf you first select MODE, CAS, and then click NUMERIC, the numeric result will directly be displayedFrank

content: My HP50g emulator was not in the RPN mode. Can you somehow get the 5/12*pi result?

content: Quote from: Hydrawerk on August 30, 2016, 10:18:56 amNo, in symbolic mode, it's not simplified that way.Don't know, which toggle or function on the HP50G to use for that, sorry.Frank

content: Thank you. Anyway, the HP 50g is probably the best calculator of this type. A calculator that can run on 4 AAA cells for long time.That HP Prime and TI-Nspire™ CX CAS are probably nice but you need a special Lion accumulator. It might be not easy to buy a new accumulator in future. My mother has a Casio Fx-7300G, that is probably 20 years old or so. It runs on two AAA cells. After 20 years it just works like it was new. No special accumulator needed.I like the HP Prime emulator. It is free from the manufacturer.http://www.hp-prime.de/en/category/6-downloadsThis link might change in time.ftp://ftp.hp.com/pub/calculators/Prime/HP_Prime_Virtual_Calculator_2016_04_14.exe
