    Hey, im in Math 12, and im looking for a graphing calculator, i wanna spend the least money possible. A Texas Insturments TI-83 costs about $140CAD.
    I found this one Casio CFX-9800G-w calculator for $50 'minimally used' from a guy in vancouver as well in the classifieds. It looked pretty cool from the description, being color and all, but then i ebayed it, and there were three results. All three were being bidded for under $10 [​IMG] http://cgi.ebay.com/ws/eBayISAPI.dll...tem=1383610896
    Would the casio have all the functions the TI does? I know the TI for sure will have everything i need.
    Thanks

    Using the TI will make it easier for you to ask friends/teacher for help if that's what everyone else has.

    I've owned casio and hp, and used many TIs.

    Casio is by far the worst I've used. The TI is pretty good, and the HP was way better than either. I don't think HP makes calculators anymore, at all. But there was finally a replacement for the venerable 48GX (what I own) that was similiar was switchable for standard or reverse polish notaion (RPN) -- Personnaly, I find RPN much, much easier to use and its one of the reasons I prefer the HP so much. It's very easy to learn, and much more intuitive.

    Just checked on ebay... you can get a 49G (which is faster and newer) for like $85. An old (well, they're new, but the calc has been around for many years!) 48GX costs about $70. Both are ~$180 SRP. The 49 is switchable to RPN, the 48 is only RPN.

    There are many programs (and games...) availible for HPs.

    I would also recommend HP - but there as a condition: You really have to be willing to spend some time tweaking a HP calc before it is as effective as a TI. The TI's are way better "out-of-the-box", while the HP needs additional programs and customization. The TI's are also faster.
    But I still prefer HP! [​IMG]

    I teach college statistics part-time and the department recommends the TI-83. It does have good graphing, but more importantly, it has all statistical tests that you would need that is pretty easy to comprehend. Setting up your data in a table and analyzing is quite easy. I can't speak for the others as I have no knowledge of them, but the TI-83 is a nice calculator.

    Okay, ill see if i can find a cheap TI-83 somewhere.. It seems thats what EVERYBODY uses :p) Even the school has a class set of TI-83, so i guess it'll be easier..but damnit, $140?
    I wouldn't have the time or knowledge to 'tweak' a HP, so thats out of the question. My parents better pay for some of it, its for my education [​IMG]

    If you're looking toward taking other Math and Science classes in college you might want to get something like the TI-86 level. We had to buy a TI-82 in HS for Calc, but when college came I ended up having to purchase the TI-86 for more Calc and Physics/Chem for the unit conversion function. If they recommend a TI calc, you probably better go along with that advice. We had class demos and programs designed specifically for the TI 82/85 series back in high school, those poor kids with the TI 81 had to manually enter the program before doing the assingment.

    hmm..depends on what you want to do after HS. If you are doing any engineering, or more calculus, definitly get a
    TI-89. If you are doing econ type things, a TI-83 Plus is prob. the way to go.

    You have to get a TI, do you know how many games have been written for them? [​IMG]

    Thanks Artur. That's sad to hear. I've always loved HP calculators.

    I dont think im gonna use it much in the senior years of college, as i am not planning to go into engineering or sciences (hey, it COULD change), im thinking of going into business.

    I know its kinda overkill, and i COULD use the class set, but then i wouldnt be able to study math at home. And anyways, ill still need it in first year math/calculus.

    Currently we're doing trig (SinCosTan, CscSecCot, special triangles, sine/cosine waves, etc) and we need it to graph stuff

    As a student currently in PreCalculus, I would recommend the TI-83+. I've been using it for the last year and it has done everything that I wanted it to. I even went for the Silver Edition for the Added Memory and Increased Speed. Though it might be an investment now, it will soon pay itself off since you will be using it later on. Since it is a TI, you can readily download many versatile programs to help in a plethora of Subjects. For instance, I had a Periodic Table on mine to aid in Chemistry last year. And when you're bored in class, there are always Games. If you can shell out to extra cash, you might want to consider the TI-89, since it can solve equations for you. If you do end up with the TI-83, please feel free to ask me any questions since I'm pretty acquainted with a lot of the functions.

    Cool, the TI-89 solves equations?! like if you say 10=y-5, then it'd solve it for Y? Sweet [​IMG]

    Yes, I'm pretty sure that's what it can do and even on a more complex level. Thought, this is only from what I recall from tangents from my Pre-Calculus teacher. I never really tried it out for myself.

    Yeah i know itll go more complex, i didnt wanna make up something harder than that :p)
    Frick, it costs $325CAD at staples (The TI89) [​IMG]
    Ohwell, i guess its the TI-83 for me

    I have a TI-89 and that thing is THE BEST investment I ever made for school. It makes everything much easier in Calc courses [​IMG]
    (plus it has lots of games [​IMG] )

    Aww man, the TI-83 Silver edition looks AWESOME, more power (arrr arrr arrr), more memory, and an organizer.. but its like $80 more than the normal [​IMG]
