Re: What do you look for when buying a calculator?

It's impossible look at just the math capabilities in a calculator (at least for me) because I use it for all purposes. I voted all of the above.

My 89 just went DOA after 5 long years of service. I love the 89, but my Calc teacher doesn't let me use it anyway...any suggesions on other calculators? I'm thinking about an 86.

After 5 years isn't it hard for something to be Dead On Arival?
I'd get an 86

I was about to say the same thing about DOA...maybe the functionality of the calculator went MIA, or the calc was KIA, but not DOA...

If you're not planning to buy another 89, yes the 86 is definitely the next best. (Please, no 83+ vs. 86 flamewars!!!)

If you love the 89, I wouldn't suggest the 86, unless you absolutely need a calc to use for Calculus...I would recommend another 89 (maybe titanium?) but if you really need a calculator for your calc class, I'd say the 86 is the next best choice. I'm not saying the 89 is better then the 86, I'm just saying that if you're used to the 89, you probably won't like the 86 too much. BTW, the 89 is better than the 86. ;)

The 86 is the best alternative to the 89 for calculus, in my opinion. It's just not really worth the hassle to get everything needed on an 83 Plus or something similar.

And if your memory has to be reset, the 86 still has some wonderful built-in calculus functions. If your 83's memory is gone, too bad...

Well, if your 83+'s memory is gone, you still have the flash memory.

If your 86's memory is gone... Eek.

Yeah, I realize that the 89 is the most amazing calculator on the planet.

I should get an HP49G+ ... my calc teacher has no idea that it has a built in CAS. What a wonderful idea!

Oh yeah...definitely. If your teacher would allow that, then that, in my opinion, is even better than the 89. It just takes a bit more to learn how to use. I love RPN in economics right now...marginal benefit/cost etc...RPN helps SO much...

In econ I'm using my HP12C ... it's got a bunch of built-in financial functions + RPN. I love RPN ... I wish Calculus used RPN.

My Dad's got an engineering version that he's had for who knows how long. Those things are probably some of the best calculators ever made.

BTW, my 83 can beat up your 86 any day! Bring it foo!

I don't have an 86...but I'm sure if an 86 was in a compitition with an 83, the 86 would have the advantage.

Alright, let's see your 83 find the inflection point of x^3 as fast as the 86. Ready, set, go!

120d, or if you're lazy, just type "0" and hit enter, but I like your answer better. ;) It's pretty clear that the inflection point is at the origin... and when it is/they are not, use your TI-89. :-P

Can the 86 do 3d graphing? The 83+ can with Graph^3...

There are SLOW basic programs for the 83 that can... cannot these be converted to 86 format... seemingly easy.

Graph^3 isn't a slow basic program. It's an app by Detached Solutions that does 3d graphing quickly and lets you rotate it. Not really useful for anything but showing off to stupid math teachers. :^)

I know that but the 86 can't have applications on it.
I was saying that the basic programs for the 83 could be easily ported to the 86 for use though it would not be as fast as Graph^3.

BTW, if anyone knows if this is true or not, pleeeeease reply to this comment.

If you are converting a source code to hex format, to include a rom call, do you just put the ROM address the call points to or do you have to include something to account for the bcall() macro???

Any help?

You're right that the 89 is much better than the 86, but the 86 is the next best.

Uh-oh! My TI-89 is over five years old, and I still use it every day. I certainly hope it doesn't die...

Re: Re: Re: What do you look for when buying a calculator?

That's interesting... I just realized that my TI-89 has had the longest active life. My TI-81 was once my active calc many years ago for a few months. Then my TI-82 probably a year or two, then my TI-85 about another year or two, then my TI-86 about a year.

But after getting my TI-89, I haven't gotten a new calc in over *five* years. I guess TI was right when they said that with Flash-upgradeable base code you would almost never need to buy a new calculator.

And the damned thing is indestructable. I'm suprised my calc didn't die years ago with the beatings I give it.

It did...they threw it at a wall and it broke...My math teacher was there...they were promoting the calc for use in schools because it was "more durable" than an 83...BTW, the 83 DIDN'T break...now THAT is effective advertising... ;)

Yeah, my TI-89 has quite a bit of wear and tear too, but it still works more or less perfectly. The most annoying things to me are a couple of tiny nicks that somehow got knocked into the LCD, other cosmetic wear, and the fact that the slide case doesn't stay on very well anymore (I have to take it off when I'm using it or it will slip and make my fingers hit the wrong keys).

They should put those hard plastic shields over the 89 screen like on the 86 and original 83.

Good point--I never had any problems with those. They're easier to clean, too. (I wish I had learned you could just peel them off about 10 years ago when I first got into TI calcs, instead of just a couple of years ago, when I rarely used my 82, 85, and 86 anyway. I always thought it was impossible to get rid of the dust that would work its way underneath them!)
