Do you know what this flash is? I'd really like to download it since I'll be taking 'Stats for Engineering' soon.Originally posted by: Syringer
There was a flash available that added a whole slew of stats stuff to the 89, which easily surpassed it over the 83. But you're right, before the flash, the 89 was quite crappy for stat purposes.
Too bad I most my math classes don't allow calcs
hmm i will have to compare costco prices to this.. and check it out. Costco has one of th best return policies i have seen.....
i'm in need of an 89

what rock have you been living under, the TI-89 is essential in Engineering stundents.
I am an EE student myself, I have the orignal and it has been a life saver.
can't go to class without it!!
I reluctantly bought a TI-89 a few months before this came out, because I needed it right away for a class. I absolutely love that calculator. I wish I could have held out for this one, but oh well.. I'm sure the new one is excellent.
My brother is taking AP Calculus BC and AP Physics B. Would this calculator have any advantages over a Ti-84 for those classes?

ellaborate.
absolutley, the 89 can do integrals and derivatives which is huge for calculus ans physics b. The 89 can also solve equations which will come in hand in physics.

It solves equations, does integrals, dirivatives which comes in handy when doing circuit analysis. It also solves equations dealing with complex numbers, which is a big part of circuit analysis. I used it to convert numbers to difference bases ( i.e. bionary, hex)

Thanks. I might think about this calc then. I really almost never needed my 83+ for calcs 1-3 but circuit calculations are different
To those who havn't used a calc like this before -
Is it amazing that it can compute complex integrals within seconds? Sure. This calculator does great things, but if you do buy it - trust me, it may become a hinderance to you. I'm an upper division (Senior) CS major/Math minor, and trust me, these calculators are not essential for anything. For the most part, if you go to a reputable university (not Devry, mind you), most upper div professors WILL NOT LET YOU use calculators in their class/on exams. This brings me to my point. If you become too dependent on the instantaneous Integral solving skills - your screwing yourself. Not knowing how to fundanmetally do basic things like integration (which is the foundation for all kinds of other math) will completely screw you if your major has quite a bit of math in it (All Eng. Majors).
For example, I started off in a course with a chap in a upper div course last semester. In the course, one of the extremely important requisites was that you know how to do various forms of integration (Parts, Partial, Frac Decomp, Trig, etc.) as well as deal with convergence and divergence. Long story short, the place the guy transfered in from let him use calcs on everything - and this course did not allow it (for obvious reasons). So the person had to drop out of the class and RE-TAKE the courses with the requisite information because he did not know how to integrate and test for convergence and divergence, he simply knew how to get the answers on his calc.
So, my advice to all of you is this : if you are in a basic class (Anything up through Calc III), you have no need for this calculator. If you are in a higher/grad level class : this thing is wonderous. It is great to check answers/methods of computation, but horrible if you actually want to learn the material.
My .02 cents.

I'll vouch for the math classes not allowing you to use calculators in exams.
However, in engineering classes, a lot of them do allow it, but you have to show all your calculations anyway. It's just a quick way to get from piont A to point B if no calculations are required.
In the work-field though, the calculator is your friend. You aren't going to do everything on paper. If you do that, (points finger ala' Donald Trump) "You're fired." Waaay too slow. Of course you want to keep a record of your work, but there are just something that don't need to be done by hand.
I myself have been using my TI-85 forever and am tempted to go and grab this. But since it's been so long since I've bought a calculator, spending a bill on a calculator just doesn't appeal very much to me. Especially since I work in the pharmacy industry, haha. =P

Well said, and I want to add to that it happens more on math class than engineering... (my friend pass his cal 3 mainly with the help of my TI92 btw =P)
I havent seen a engineering professor who won't let their student to use calculator. It's a disaster for the TA to grade those questions when it propagate errors...
Gosh darn it. When I was an undergrad, EE Pro wasn't free for the TI-89 and I wasn't ready to shell out the money for it. Now after I graduate they give it away for free???? Oh well, at least I learned the equations and still remember them now. Those programs on the calculator are just a crutch in school. Once you are in the real world, they would speed things up where time is of the essence. But in school, theory is important so it would just make it harder for you to learn (IMHO).
Back to this topic of this post: if you don't have this calculator and plan on doing advanced math, engineering or similar disciplines, this calculator is highly recommended. Plus the Titanium for $120 is a deal you can't beat.

Well put. I've got a few friends who are in EE and CE, who use calculators religously in courses - which is fine because the bigger problem is dictated by long integrations, physics involving integration and convergence/divergence, and applied Differentials. Your calc, with applied calculus (in Eng, CS, Physics,etc), is definately your friend.
My point is that those who are just starting out in basic courses of Calculus probably should not get a tool like this because it is way too tempting to use it to "just get the answer" rather than learn, for example, how/why basic integration works. I see way too many high school kids at the Community College I tutor at come in with Calc AB experience, with absolutely no idea about how an integral works, or a limit, etc.
With the basics (Beginning Calculus Series courses), a calculator like this is unnececcary and most likely will be a hinderance to you. On the other hand, as nikkai put it, in applied disciplines - your calculator is definately your friend and should be used whenever possible.
In my opinion, here is where/how you should you use a calculator:
Algebra -> Calc for statistical purposes is nice (Basic four function, or 83-85 for graphing applications).
Calculus Series (I-III) -> 83 or 85 for graphing, calculations, etc. 89 IS NOT NECCECARY AND SHOULD NOT BE USED. This series of courses is meant to reinforce fundamentals of Calculus (Limits, Integrals, Conv vs. Div, DE, etc.), and having a calculator doing the work for you does NOT reinforce these fundamentals.
Applied Calculus Classes (Eng, Physics, CS, etc) -> 89 or Hp49g+ is great when you have issues involving long proofs, integrations, derivations, etc.
The TI-89 made me an engineer For all my upper division classes I was allowed to use the TI-89 with out any problems as long as I showed my work. I was lucky enough to use them in my calculus classes etc. However, the Math departments changed their policies and now the TI 89 is not allowed on tests. All the engineering programs to my knowledge let you use the TI-89. For those that think they can get by just be using the TI-89, well for the most part you can. Eventually though if your just punching numbers in not knowing whats going on you will be in trouble your senior year or if you go for your masters

It's like using a scientific calculator in junior high. Sure you can do long-division by hand, but if you've already gone through the classes and have the ability, there's really no reason to keep writing it out everytime. It wastes your time and the person who's grading your paper.
IMO, it's ok if you forget some of the harder integration techniques (I couldn't do a trig substitution right now, or maybe even a hard IBP problem), but it doesn't bother me, I've been through Calc III and Diff Eq's without a calculator, so I've paid my dues. All the EE courses I've taken (at a school with a Top 10 undergrad EE program) either allow graphic calcs (including Ti-92's), or make the integration fairly simple (u substitution, simple reverse derivatives).
EE*Pro has some stuff that you could use as a crutch in a Circuits I or Electronics course (with Op-Amps in particular), but you still need to be able to do the analysis and recognize what type of problem it is. My $.02
