Best calculator??

I was wondering, what's the best calculator for engineers that is good to use for Calculus and Physics.

    Well if you're talking about a non graphical one I would strongly recommend a Casio. First I bought a Texas Instruments one (called TI-30X) which I personally did not like at all. My math teacher took one look at it and told me to throw it away and never use it again. He told me to buy a Casio FX 991MS and I did. I love it it has everything a non-graphical calculator would possibly have, it solves quadratics, matricies, vectors, eq'n with multiple variables and more. Seriously I'm so into this calculator I'm going to buy another one just in case my first one got lost and I couldn't find one near my university!

    On a side note I haven't gone to university this calculator has only been used for Calculus 1 but I'm pretty sure its one of the best.

    Any scientific calculator is fine. Calculus shouldn't require one, and if you get to take a numerical methods/analysis class, you'll end up using a full computer anyway.

    If you get into higher level mathematics, you may find TI-89's ability to do symbolic evalution helpful. Every engineering student I knew had one. I resisted for a very long time, since I had graphing calc software on my palm pilot that did most of what I needed. It wasn't until I took Complex Analysis (a senior level math course) I finally broke down and bought a used TI-89 because I couldn't do symbolic evaluation otherwise.

    I've used a TI-83+ for 5 years now and it's been pretty good to me. It is VERY helpful to have a graphing calculator rather than a scientific calculator for calculus. For physics, it won't matter as much. At some point in your engineering courses, you'll probably have to solve a large systems of equations, and the matrix feature of the TI-83+ will become very helpful.

    I have a TI-84 Silver Plus, and I love every square millimeter of it. I've had no problems with it. Granted, I've only used it for high school physics and calculus, but I love it.
    Of course, I think Texas Instruments rules the world, but I'm probably a little biased... :)

    I swear by my TI-89.

    It does everything a Ti-83 can do and a WHOLE lot more (calculus, linear algebra, trig, automatically convert units and even have access to Engineering books for equations).

    TI-89. I'm convinced it's worth .1-.2 GPA points just on its merits. I use an 83+ and there are several classes where my grade would be higher if I had had an 89.

    It reallly depends on the instructors, because some don't allow graphing calculators. I would recommend a ti-89 and some regular non graphing calculator that can do sin,cos, tan for the those classes that have calculator restrictions.

    I use a TI-89 and an HP33-s. Some problems call out for the 89 - especially when you have large numbers of data to use the same operation on. Other times, the RPN of the 33-s is much more useful!
  • CorbettCorbett Registered User Posts: 2,706 Senior Member
    The best calculators for number-crunching are those with an RPN mode, like the HP-33S (scientific) or HP-50G (graphing). The 33S is the most powerful scientific on the market: it can be used in either RPN or algebraic mode, and it has programming capability (which Casio and TI scientifics lack). The 33S is not as powerful as a graphing calculator, but it can be used in many situations where graphing calcs are banned, such as engineering licensing exams.

    The best calculators for symbolic math are graphing calculators, particularly the TI-89 or HP-50G. The 89 is noted for its ease of use, and is very popular with students. The 50G is more powerful and flexible, but it has a significantly steeper learning curve, and is more commonly used by professionals.

    The 89 and 50G also support calculations with units, which is handy for engineers. The 50G has the broadest units support, but the 89 probably has all the units you would need as an undergraduate.

    Real engineers use Hp's. New interns and students use Ti. you can tell whos the new hire, by who is carrying a Ti.

    I use the Hp 50G and the 33S.

    I wont debate this subject here as I know im right, but HP makes the best calculators, the only reason Ti is popular is due to them buying out the market with bribes. There calculators actually do suck.

    If you are looking for the best graphing calculator its either the HP 48GX or the Hp 50G.

    For a scientific it is byfar the 33S.

    If you plan to take the FE and PE then buy the 33S as the Ti 36 is awful.

    ti-89 titanium rocks my socks off.
    yes, i can be a geek.
  • chaoseschaoses Registered User Posts: 1,039 Member
    the best calculator is matlab :D
  • abaddonabaddon Registered User Posts: 3 New Member
    HP 50g all the way, it is far more powerfull than a Ti-89. Someone who knows what they are doing can do complex mathmatics with an HP so much faster than with Ti. The only reason the school system in the U.S. uses TI calculators is because when they got new math curriculum in the 70s TI payed off people to only use TI for the text, even though they are no good. TI is only a player in the calculator market because of backdoor bribery.
