Not to sound like an old fogie here (I'm not that old), but why do you need a graphing calculator? A regular calculator with all of the scientific functions is plenty. I never needed a graphing function except to help me when I didn't understand a graph and then I would either borrow someones or go to the computer. I went through college with guys that paid hundreds of dollars for HPs and TIs that they never used 10% of it's functionality. My advice is save that money and buy a good sinle line calculator.

You'll need whatever the department uses. MOST Calculus and physics courses that I know of are taught with a TI-83. Great calculator...the Silver Edition is a very nice machine. I used an 83 and a Voyage 200 (which used to be called a TI-92) in Calc 1 and 2 last year. I like them both, but some colleges won't let you use anything over an 83 on tests and the like.

The Voyage 200 (TI-92) has too many options which will allow cheating- or at least an unfair advantage. Some colleges, I understand, use Hewlett Packard. If it were me, I'd either ask someone (e-mail would work) in the department at the college you are attending, or look at the college catalog to see if I could discern which they use.

Hope this helps

As I have seen some other different replies, I am going to repit what Fred has said, which is all gold. He knows what he is talking about, and I know too because I have survived 5 years of study with a CASIO fx922, which is a single calculator.

Fred and Clausius you guys are right. I've e-mailed a professor in the engineering department of my school and he has told me that I would only need a scientific calculator. Nearly all graphing will be done on the laptop with software supplied by the school, rather than on a graphing calculator. I was going to spend 150 bucks on a Ti 89 , but now I'll just get a much cheaper Ti 83. That's 70 more bucks into paying my tuition .. thanks guys.

*counts on fingers*

seven years old or so. And honestly, I didnt need much of the functionality available neither.

HOWEVER

Using your imagination to find out the purpose of the diffrent functions was half the fun. I tell ya, after I sold boxes and boxes of candy to get my TI-83, I dived into that sucker and programmed the pygathorean theorum the first night I got it.

Ah memories.

Please don't make general statements like this. I have never gotten below an A in any class in which graphing calculators were permitted (including all of my physics and engineering classes), and I use a TI-89. As with every tool, it all depends on how you use it. On the one hand, if you only do simple calculations with it, then you are obviously not utilizing it fully. On the other hand, if you're using it to perform numerical integrations which might otherwise by cumbersome, or you're using it to simplify complex statements which might take a long time to do, then you're using it wisely. I can't begin to tell you how much time that thing saved me during exams.All students that I have met with HP and all these stuff of expensive calculators were all of them bad students.

I am not making ANY GENERAL STATEMENT!!!!!!!

Re-read my sentence again!!!. I am not saying: "all students that have those kind of calculators are bad students". Not quite. I am saying: "all students that I HAVE MET and have this calculators were bad students". Where is the general statement?, I don't see it. It's a pity you know how to handle your calculator but you don't know how to comprehend the comments of the rest of the people. :yuck:

I can see where you're coming from on that one. The only thing I see with these types of calculators is that they are marketed primarily to students, especially high school students. I have NEVER seen an add for them that depicts an engineer or engineering student churning out integrals as part of an ad campaign. I see this as a real pitty. IMO it's another step in dumbing kids down for the sake of expediency and ease. In most people's hands, these are small idiot boxes that the kids simply punch buttons and parrot what comes out. We're bringing kids up through the ranks already dependent on something other than their brain.Wrench said:

If I had a kid who said his math teacher is making him spend $120 for a calculator simply because it graphs, I would be standing on that teacher's desk demanding to know what the hell they are trying to accomplish. Actually, now that that has been brought up, does anyone know why some places require an expensive calculator like that? I am interested in hearing the reasons why. It will be good preparation for if I ever have a kid.russ_watters said:requirethem, so the best advice really was to find out what the department (and that means your math department too...) recommends.

In general, I don't see the use of a calculator as being wholly different than using Matlab (or Excel) to solve a problem for you. Its just another tool.

Brews, the one nice thing about slide rules is that you can actually argue that 2+2=3. I don't think I'd want to go back that far in time. From what I have been told about the old days though, it kind of looked like the old west with all the engineers' slide rules dangling off their belts.

Well said! I'd do the same!.

yeah, I was imagining that. You and your sharp riding across Manchester fields, like Clint Eastwood in the ugly, the... and the.... (don't remember).

TA-NA-NA-NA-------NA-NA-NA (BSO Ennio Morricone :rofl: )

I do admire some of my professors who didn't have any calculators available and employed those fatal slide rules.

And Russ, there is a crucial difference about using Matlab and a graphic calculator. While you must switch on the PC to use Matlab (it takes time and effort), you can make an undiscriminated use of the calculator and you will be soon acostumed to use it when you will face a difficult equation instead of solving it with your hands.

I would like to make the statement that anybody that is wasting time doing number crunching by hand is retarded and I would personally like to welcome them into the 20th century. After which the 21th might be the next step. I see this allot when Nerdy teachers at high schools try to impress their students.

Everybody is talking about graphing. Nobody uses that. What people use is the solve function.

solve(f(x)=g(x),x)

this can save tremendous time on a test. Plus unit conversion. and the fact that you have a lot of data easily accesible and presented on a big screen.

I am a 4.0 student in grad school with a voyage 200 calculator (Cluassius) and I doubt if this would have been a 2.5 without it.

The whole point to this is learning and understanding the subject being taught. Mnemonics, jingles, writing equations on strategic spots onPenthouse pinups to help visualization ( I really know someone that did that) singing the ABC song..whatever it takes to be able to learn to use mathematics is what counts to me.

On a side note, the Fundamentals Exam and the PE exam will not allow you to use aforementioned graphing calculators.

I'd go for the Faber Castell 2/83-N Novo-Duplex. It's slightly longer and wider than your traditional 25cm device making it easier to read at 3 in the morning (but not nearly as cumbersome as though 24" monsters). It has 8 log-log scales and does just about anything you need, including solving quadratic equations. The only odd thing is it follows the European custom of putting the trig functions on the body instead of the slide.

Actually, I'd recommend the TI-86. Complex numbers, the ability to solve simultaneous equations, and the constants (built in and custom stored) make it a lot more useful than just a standard scientific calculator.

If you're forking out for the TI-89 or one of those big clunky blue things, learn how to use them! I amazed at how many people are cursed by a calculator they don't know how to use! When I hear them cussing out their TI-89, I get this urge to rush out and buy one - I feel like I'm missing out on some incredible experience.

EXACTLY!!! Anyone going into engineering should serously consider the Ti-86 IMO. The custom menu is great quick and easy to use along with the calc functions and Bob's points.

PS. I hate 89's becuase they are little computers withouth the keyboards---unweildy.
