Is there anyone out there that knows how to operate the 48GX?

email me your address, I'll mail you a free set of manuals. (US only)

Actually I have the manual but it's so confusing to me.I was hoping that there would be someone that I could e-mail back and forth with specific questions on operations. I'm an engineering student and really want to use this calculator instead of the TI 89 which is what all my teachers use.

You may be better off searching first and then posting questions about the 48GX at comp.sys.hp48

http://groups.google.com/group/comp.sys.hp48/topics?lnk=gschg

This group is very knowledgable when it comes to the 48 family, but I would say prefers RPN calcs, collecting HP calcs, and discussing math, engineering and other trivia. The comp.sys.hp48 group is a much better resource if you are in school and/or just learning the 48 series.

Do you have the Quick Start Guide? That might help matters compared to the thick manual. If you have any specific questions, post them here, there are plenty of 48GX aficionados in this forum..

You are not alone. I have been slowly learning my 48SX for about 2 years now. Some folks seem to pick up and learn how to use these 48/49/50 series models so easily, but for me they are not very intuitive to use, other than for some simple RPN math. Still, I press on, because of the power that these machines hold.

It seems to me the biggest initial hurdles were understanding that everything is an object, and everything is entered postfix, even STO and RCL.

I was lucky. I worked my way up slowly via the following machines: HP-25-->HP-11C-->HP-28C-->HP-28S-->HP-48SX-->HP48GX. Still the transition to a HP-28C (which is simpler than a 48GX) was a big jump.

For me understanding the VARS menu and the directories in the calculator really helped a lot (48gii but same thing or this discussion).

I have a directory that I call Junk where I sit when just mucking around in general. If I have a specific type of problem I'm working on then I will set up a directory and maybe even some sub directories and only go there when working on those problems. Otherwise, I find my list of variables gets unruly very quickly. I purge the junk directory regularly.

Have you worked with any other HP calculators in the past?

This is my first Hp calc. Actually this is my first graphing calc. I bought it at a garage sale, I have both the huge manual and the quick start one. I have used it in my trig class and college algebra. In the college algebra there were a couple things that I couldn't figure out. Now I'm in calculus and getting worried that I won't be able to use it because no one knows how, not even the teacher. I would like to keep it because I've heard so many great things that it can do, and that it's great for engineering students. But now that I've found this forum I will just post my question/problem here and see if anyone can help me. You people are great.
