Discussion Overview

The discussion revolves around the choice between the HP 50 and the TI-89 Titanium calculators, focusing on their features, usability, and suitability for high school and college-level mathematics courses. Participants share their experiences and preferences regarding these calculators, particularly in the context of calculus and science classes.

Discussion Character

  • Debate/contested
  • Technical explanation
  • Exploratory

Main Points Raised

  • One participant expresses frustration with their HP 49g+ and seeks advice on whether to switch to a TI-89 or an HP 50, noting the difficulty of using RPN mode.
  • Another participant suggests that if one has not learned RPN, there is little point in choosing an HP calculator.
  • Some participants highlight the TI calculators' reputation for having numerous supplemental programs that can aid in various courses, referencing a specific website for resources.
  • There is a discussion about the perceived superiority of the HP 50 due to its RPN feature, though others question if that alone justifies the choice over the TI-89.
  • One participant warns against the TI-89, stating it is too powerful and banned on many tests, while others counter that it is allowed on major standardized tests.
  • Several participants note that TI calculators have better community support and more third-party applications available compared to HP calculators.
  • A participant mentions that they used an HP48 in college and found it to be the best calculator they ever had, emphasizing the importance of learning RPL.

Areas of Agreement / Disagreement

Participants express a range of opinions, with no clear consensus on which calculator is superior. Some advocate for the TI-89 due to its community support and applications, while others support the HP 50 for its RPN feature. The discussion remains unresolved regarding which calculator is the better choice overall.

Contextual Notes

Participants mention various factors influencing their decisions, such as test regulations, personal preferences for RPN, and the availability of third-party programs. There is also a recognition of the importance of understanding the calculator's operation rather than relying solely on community support.

Hello I am new here, so please don't kill me for not searching around before posting this. I am a bit stressed out and short on time.

Alright.

After receiving an email from HP saying my warranty has expired, and seeing that none of their trouble shooting techniques could save my HP 49g+ I am left in making one decision. It is time for a new calculator. I have had my HP 49g+ for about 4 years now. I got it when I was in 7th grade for a geometry course, and was told I would not need another calculator as long as I took math. I guess they were wrong.

Anyway, throughout that time, I have continuously used TI calculators as well, mostly TI-84s and TI-89s. I find they are much easier to use. It has always been difficult being the black sheep in my math class, the guy with the HP calculator that no one knows how to work. Even my Calculus teacher looks at the HPs as if they were foreign objects. So, I am now faced with the decision with choosing between a TI-89 and a HP-50. Due to recent problems with my HP-49g+ I am a bit hesitant to stay with HP. I have had my calculator all this time, and have still yet to become comfortable with using RPN mode. This is something that HP is known for in their calculators which I can not use to this day.

I am sure many of you are familiar with both TIs and HPs. I am a sophomore now, in a college-level Calculus course. I will need a calculator that should last me through the rest of high school (Calculus BC and Multi-Variable Calculus) and possibly college. Are the HP 50s good calculators? Do they have as many problems as the HP 49+g? What are the main upgrades/differences between the HP 49g+ and the new HP 50, besides colour. I am willing to learn, as long as I get the best calculator with my money.

Lots of question, and little time.

I appreciate your responses.

P.S. Many of my friends who own TI-89s say there are a ton of programs that are beneficial for classes such as Chem AP, Physics, AP, and other college-level science courses. Would a TI-89 be superior to the HP 50 when taking this into consideration?

If you have not learned to use RPN, there is no point in having a HP.
 
I can't speak for the HP 50, but TI calculators do have a reputation for having lots of supplement and third party programs that will help your courses. ticalc.org is one such site where you can find these packages.
The only reason I would ever switch to an HP calc is if I wanted to use RPN mode, other than that, I'm happy with my TI 89.
 
anyone use casios? i just got a cfx-9850gc plus today.
 
So besides having the RPN function (which I am not completely amazed by) is there anything else HP 50s have which ousts the TI-89.

Since my Calculus class will not wait for me (poor sarcasm) I will need to make my decision by tomorrow most likely. If the only thing people can say the HP 50 wins is the RPN, then I will probably go with the TI-89. Since I am going to be taking classes such as Chem AP, I guess the TI-89 would benefit me more?
 
RPN alone makes the HP a superior calculator, other features are equal.
 
Well, I need to make my decision tonight, so I can get the bloody calculator shipped in time for an important Calc exam.

At this point, I am leaning towards the HP.

Can I get some definite opinions/stances from people.

Thanks
 
Don't get a TI-89, these calculators are too powerful and are outlawed on many tests which allows TI-x | x < 89.

Do switch to TI, they have better resale value and are recognized by more people. Having an HP is like having a Mac, people do it for various peculiar reasons but what you really lose is community support.

Tests are not the problem.

The TI-89 is allowed on the SAT, SAT II, Calc AP, and my Calc teacher's tests. Anyway, I think I am going to go with the HP. Any objections?

The 89 is allowed on most national tests, as GreekXboxMaster has just pointed out.

I have no objections with your choice of an HP. You may find RPN to be a big plus if you ever plan on using RPN mode. However, I'll also add this - the TI calcs have way more community support and tons of third party apps.

So if you have a HP you cannot rely on the canned solutions provided by the teacher...

Guess that means you have learn the material and understand the operation of your calculator. I would say that if you have to rely on "community support" you are not learning what you need to know.

You can download multiple apps for the TI-89's that will allow you to use RPN mode on them. Consider yourself lucky, we are not even allowed calculators on our calculus class. Sounds harder, but I find it better because you are forced to learn the concepts rather than to rely on a crutch.

I used an HP48 with expansion slots in college.. still have it.. best calculator I ever had. And once you learn RPL you'll never go back.
