Calculators

    I'm currently studying Electrical Engineering and my calculator is holding me back. I will probably buy the Casio fx-991MS. Has anyone used it for the likes of complex numbers, calculus, vectors, etc? Would anyone recommend the Casio fx or have any other recommendations. I'd buy one of those TI ones if I was minted, sadly i'm not

    Don't know the MS, but I used the (more expensive) fx-991ES for an Engineering degree and it was grand. The Complex functions were good enough and the Matrix functions came in handy too.

    The problem with more powerful calculators like TI-83 or -84 models is that they're programmable, and thus prohibited in most exams. I have a TI-89 which I couldn't really use at university. Cost, too, as you mentioned: another student dropped my first Casio on a concrete floor, but replacing it wasn't a big deal.

    You are the type of what the age is searching for, and what it is afraid it has found. I am so glad that you have never done anything, never carved a statue, or painted a picture, or produced anything outside of yourself! Life has been your art. You have set yourself to music. Your days are your sonnets.

    Yeah I think even the graphing calculators are prohibited in exams, so even if i could afford one, there wouldn't be much point.

    I think the ES has more functions than the MS. Argos sell the ES for €30.. I'll probably go for that so.

    When you say it was 'grand', was there anything you didn't like about it? Or did it not do certain things you needed?

    I don't think I could have found a better calculator than that, for what I was doing (civil engineering, which included some electrical modules). You enter Vectors and Complex numbers as written, basically, which I liked.

    I was referring to the limitations inherent to a non-programmable calculator, and the need to take hand-written exams. I never enjoyed that part of unversity, and real work isn't done that way. I'm much happier using a computer with MATLAB. ;)
