This is what i must think about. My current calculator, the TI-83+ model, is still going through several reprogrammings. Since this model lacks RAM and Archive memory, i might as well get a TI-92. But for the moment, i okay with this one.

I bought my 89 a few months ago, since then I've pretty much stopped using my 82, I use my 85 mainly for programming, I haven't had to time to master 89 BASIC quite yet. But my 89 is the best calculator I've bought, It has the CAS and Pretty Print, and all sorts of other functions, and availible programs to keep me happy. God I just LOVE my 89! It rocks! :)

So, have I ever told you about the nights I spend with my 85, just me and my 85 in bed. Yep, we spend a lot of time together in bed. Strangely I still suck in Ztetris and Galaxian. That's probably more than you ever wanted to know :)

Rocks? Ti89 is heavy metal!!!!
Every day I use my TI89 I can't believe it, do you know what it means to change from a 9850G to a TI89?????? Here, people only knows Casios and some HP, to give you an idea, a friend of mine used to laugh with his HP48G, because “ is the best calc in the world it can find the derivative formula of a function ”. So, I asked him,
-“HP48G , eh, mmmm , memory??” so, he answered : -“It has more memory that you can imagine:32kb and you can do 3D graph and play games using Basic language !!!!! .
So, I said -“mine has 702kb of archive memory and 188Kb of RAM”
-“HA HA!! Good joke!!”
–“no it’s not a joke.” I turned my TI89 ON, then on the homescreen; sma() and he couldn’t believe it
he played sonic, Mario, and solar striker without laughing at all .
-“Man, this HP I have just sucks, congratulations, I didn’t know there was such good calc ”

The TI-89 is the best calc on the planet. I never regreted plunking down $150 for that thing. It does almost everything I can imagine and is very fast in the process. It blows away any other calcs.

I should mention, though, that I think TI's other graphing calcs are a bit over-expensive for what you get. Before I bought my 89 I had bought a Casio CFX-9850G mostly becuase it costed less than a TI-83 or TI-82. It actually graphs some things (sine waves, etc.) faster than my 89, almost twice as fast. It has generally been a good calc, but my TI-89 has replaced it for just about everything.

None of these options fit:
* No, I like my calculator as it is.
* No, I cannot afford another calculator.
* Maybe, It depends on how much improvement there is.
* Yes, I do not like my current calculator.
* Yes, I buy every calculator TI makes.
* I do not have a TI calculator right now.
But yes, I am planning to buy another TI-Calculator.
My next planned purchase, a TI-68. Others planned, TI-82, TI-89. And of course, the Plus module for my 92. I own two TI-85s. Keep one at work. The other to and from work. My TI-86 was bought to replace my 85. But since programs written on the 86 cannot be easly ported to the 85, I do my programming on the 85. I like my TI-92 over my HP-48X. I have written/translated programs top run on the HP, but I have done no programming on the 92 except one picalc program written for the 89, I have edited so my 92 can see the whole answer. Other than that edit I have done no programming on my 92. I have ported porgrams for the 85 to a 82 format (I don't have an 82 yet). And ported an 85 program (Basic Quadratic Solver) to the 92. And and of course to my 86.

For information on the (soon to be obsolete?) TI-68: http://www.ti.com/calc/docs/68.htm

It has double its pi percision for its trig calculations. For example the correct calculation for the sin(100000000) i.e. radians is .9316390271097. Most hand held calculators get .9316414772581. The TI graphing calculators get: .93163910531978

Hey, whatever, I believe you :)

Actually, I believe it since TI is the best Calc manufacturer, definitly, and we should all get at least one of each of their calcs.

I don't believe him. Let's have a long, drawn out arguement concerning the variations in the ten millionth decimal place in certain calculators, depending on pi precision. Personally, I plan to get very upset and boycott the TI community altogether over this issue. Paul's ideas are an outrage.

If you don't realize that this was a joke, you have problems.

According to my TI-83, sin(10^8)=.9316391053

I have a TI-82, it gives .9316391053 too. But it has internally the value of .93163910531978. Check this on on your TI-83, SIN 10^8 - .9316391053, you will get, 1.978E-11 as the answer. The HP-20S gets 0.93163902711 which is the correct answer. But the new low cost HP-6S gets 0.931641418 just like any other hand held. The Correct answer is .9316390271097. The extra digits ...097 can not be gotten out of an HP. The 100000000 radians is really 1.1988975190857 radians, so enter in as SIN 1.1988975190857 on a TI-82 gives .9316390271. The problem is not a normal one, to enter 100000000 radians. But it is a test of computing accuracy of calculators. This problem requires PI to twice the accuarcy of the calculator, to get it right.

Actually the 89 can be more accurate than that. On the 89, sin(100000000) is sin(100000000)
You can't get more exact than that.

I hadn't checked my HP 48GX, but it gets the answer for the SIN(100,000,000) in radians correct to all eleven places (rounded off of course): 0.93163902711

Of course it is limited to 11 places. And trying to find the extra internal digits. No.

Even though the TI-92, 92+ & 89 don't have the double pi value built in like the TI-68 and of the HPs. The TI-92, 92+, and 89 are still superior in ease of use and computing power. More precicion for the most part. Understand while I like my TI-92 better. I still like my HP. But the a 1 mag memory card is like $360 the last I checked. And programming manual is extra. Good thing I know how to program older HPs like the HP 41. And know how to do FORTH. Now that is an Idea, FORTH on TI. There is a TI FORTH for the TI-99/4A. It might be nice on a calculator.

I don't think RAM prices decreased a lot. By the way, I don't think TI's E-module was any cheaper (US$/MB). If you really need memory, it's probably better to get a HP49.

However, the TI still returns more digits (about 15).

Of course I would like FORTH on a TI (although it's not very likely, because it's RPN)... The HP way is very close to FORTH entry actually.

I really like the TI-89/9x because it just returns answers in a very shnort time. On the other hand, I love HPs because of RPN and ability not to have a result computed at once (but clearly if you already know *how* to do, the TI or a Maple-like are a lot quicker).

I won't buy an upcoming TI at random. I'm very suspicious :o) !

I hadn't known about the HP-49G except it was mentioned in another place here. Checked out the HP web site to find out more about it. The main advantage was it has more memory built in. But can't do much more then the HP-48G(X) that I could see. I looking in stores today for TI-68's. I have one or two more stores to check before I just order it direct from TI. I saw the HP-49G ($179.95). The HP web site had a warning to only use the right RS232 cable or it can and will damage it an one other. I didn't take time to look closely at it. I also saw strictly algbraic HP-20S, nice ($34.95 on sale). The TI-68 goes for $49.95 or so. If can find one. Some of the TI low end calculators TI-30a series (not the II) have logrithmic limitations droping to 3 place accuracy on the 11 digit display. On the old TI-55 II and TI-54 (LCD versions not older LED type) had the same problem, it was documented back then in the manual.
For example (1.000000001)y^x1000000000 would give 2.71919279 as the display answer. Cheaper calculators (not TI) would give correctly 2.718281827. The TI graphic calculators don't have that kind of problem. Good thing. I like my TI-92 better for doing symbolic stuff easer and better than the HP-48GX. I still want to get a TI-68 though.

I am a toolprgrammer, I am currently employed as a CNC (Computer Numerical Control) mill machinist. I use the calculator to estimate metal remove rates. And some geometery problems without having to go on the computer CAM (Computer Aided Manufacturing) software. All the routines on my calculator were written as needed. Most were rewrites from programs I had written to use on my TANDY 100. From when I use to just do the tool programming in an office for the machinists and operators. But now, where I work, I have to do setup and operations too. There are woman tool programmers (I have read about), never meet one.

I am a chemical engineer. I use 2 86's, an 89, and 92+ at work. I also own an 85, 86, and 92 from my high school and college years. I also use my graph link quite ofton with my notebook. I use one of my 86's all the time, it goes wherever I do. I have overclocked it, and expanded the ram to the same as the 89 (thanks to my buddies in the electronics department at work). My second 86 I use with a CBL unit. I have found I get fatser results using this setup than a computer and data acquistion system. My 89 is setup to do more advanced calcualtions and 3-d graphing, I use it mostly when I am in the lab. I use my 92+ when I am at my desk, becuase it is so large and bulky. The nicest thing is downloading my work to my notebbok at the end of the day and taking it home. This also makes it much easier to port from calc to calc. I program for all of my calcs, and used to for the 82's back in high school. The only problem I have found using these calculators extensivley at work is the hell I get for it. Most of the other guys use HP graphing calculators and their pc's. That is the reason I am senior chemical development engineer and they are my slaves. The Ti's are also great for playing games during boring meetings. (I am just as bad as the students out there. Except I get paid to not pay attention and play games. :P) I get most of my games off this website, as I don't have the time to make my own. So keep working on those 86 and 89 games. I have one suggestion for you game programmers out there. Make a false screen of calcualtions so you can pause the game and hide the fact you are playing games when the boss or teacher walks by. As for new calculators, my suggestion for Ti is to make a backlit screen for playing in the dark. That would keep my interest on the game when the lights are turned off and some fat bald man is showing slides or using the overhead. See there are some cool jobs in the world if you work hard enough. If you ask I may tell you what I make now and what I started at.
