    Oh Happy Day: new calculator =)

    They say you know you're an engineer when you've used every single function on your graphing calculator. Goodbye Ti 82, handed down from my older brother and sister, hello brand-spankin' new complex-coefficient simultaneous-equations solvin' Ti 89. =)

    It doesn't have a yellow case, but I think you know which calculator it is. I'll now quote what I once saw about the TI89
    Don't challenge the TI89. It's a massive BEAST of knowledge.
    I have to say... I agree.
    Away.

    Yes it is rather powerful and quite the investment. Though perhaps I should have spent more time determining of my 82 could be squeezed a bit more, I already had it do real simultaneous equations and complex division, but it wouldn't do general complex expression simplification, or autonomous partial fraction decomposition! =) Yeah! I should have asked you guys, but well I would have bought it anyway, hope it was better that much than the 86 model. Anyone know how you could do complex coefficent matricies on the 82 without splitting it into a real system and a complex system? That's too much work! =) The menus are amazing, and... this here engineer is happy!

    Yay!

    the TI89 is a nice calculator. I've had it for a while now. I'm kindof excited about using it again when I start college soon. I still have my 83+ and probably could have gotten by in hs with it; but the 89 was a gift, so I figured I might as well start using it and get somewhat familiar with it.

    i think i've become a little too calculator dependent. i need to get used to not using it unless necessary. I haven't strayed too much from that, but I think that I could do some stuff that I've been using the calculator for without it.

    Yeah, the extra $50 is definately worth it. The 89 is head and shoulders above the 82-83+. The only time it fails is when high precision graphing is needed, overflows occur, or you use one of their various described inaccuracies (i.e. 0^inf).

    Well, I meant as opposed to the 86, didn't know too much about it going in, but it's not that bad cost wise anyways, and it was inevitable that I upgrade eventually anyway.

    Funny thing you should mention, my physics professor last session was a firm believer in not using the calculator as a crutch for exact calculations, and made us improve our estimation skills by disallowing calculators on quizzes. It worked, so now I know the distance of a hall to be about 10 meters, the middle finger to be about 1 cm, and the weight of the human head to be 8 pounds. =) It was effective, and he was a rather kooky professor at that.

    I was gonna buy the 89 or 92 but the math teachers at my school seem to have a problem with anything above an 83+ SE so I had to settle for plain old 2D graphs, its kinda depressing. Hopefully in a year or two I'll go get the most expensive one I can and hopefulyl get a lot of games for it. I wish the TI calculators had support for memory cards.
    Give me a bad reputation!!!

    I've had an 85 for about 8 years now. Never done me no wrong - I'm on my second one.

    I've had a TI82 for 8 years - still works fine, after a ton of abuse. I just got an 89 last year, and I love it... 'twas enough to make me stop using the 82.

    yeah, get used to that. Ive had very few courses that allow calculators. Stats is the only course that you can be sure calculators are allowed.

    I got the ti-89 last year... it's a fine piece of machinery. Where all other portable computers drop their price every year, the TI-89 is still going strong at ~$150.

    Its amazing the programs you can get for it. I've got an ebook reader I use occasionally.

    It's fun until you find out that none of your college classes allow the use of said calculator on exams and homework.

    FYI: The 89 plus is more powerful than the 92.

    I'm now gonna enter engg. college now where calculations are tough enough that calculator is allowed.
    I've bought myself the "Casio fx 100 MS".
    It's amazing!It can solve simultaneous eqs.,quadratic eqs. and lots more.
    The happy days are certainly here!

    I have NEVER seen an amazing Casio. I've never seen a good one. I've seen lots of bad ones. Did you, by any chance, compare that Casio to a TI before your purchase?
    Away.
