There's a free trial version? Could you point me to it if possible? Btw, do you know of a good resource that compares Mathematica versus Mathcad or any of the others? Thanks again. And it seems to be pre-loaded with physical constants, which I use all the time. And yes, you're right, the TI-89 can handle three-digit exponents, while the TI-84 and others cannot, which is a true bonus. SYMBOLIC CALCULATOR FREE WINDOWS WITH UNITS MATHCAD HOW TOA class I'm going to take doesn't allow them, but I can still buy it, use it and borrow the allowed TI-83 from the math lab for tests, and hopefully the TI-83 is similar enough in basic functionality that I'll know how to use it during a test. Thanks! I've heard great things about the TI-89. MathCAD also gives the correct result, but only after I format the result correctly. On the TI-89, taking the fourth power of Plank's constant gives me the correct answer (1.92764*10^-133), the Casio gives 0. You should check the requirements of exams in your class though, because if programmable calcs arent allowed, the Casio fx-115ES is what I would recommend. They'll do everything you need, and being able to write (and download) notes and programs for the calculator is invaluable. Well I would highly recommend a TI-89 (or comparable HP programmable graphic calc). If you have good eyesight, the iPod is readable and much more portable.īoth Spacetime and Maxima may be an issue for students because they may not be allowed when taking tests. The Apple iPad is another way to go, but I concluded it is harder to tote around, so I would be less likely to have it at all times. SYMBOLIC CALCULATOR FREE WINDOWS WITH UNITS MATHCAD PDFThis is cheaper, and now I always have this book, as well as the rest of my PDF library, in my pocket. I spent $40 for the eBook, rather than over $100 for a real book. The other day I bought my first physics text book this way. I'm just really impressed) I also loaded Kindle on the iPod and started getting free ebooks that are available. With all of this, as well has hundreds of songs, and the obligatory 79 episodes of original Star Trek loaded, I still have only used less than half of the 64 GB of memory. I also have physics video lectures (about 200 hours !). SYMBOLIC CALCULATOR FREE WINDOWS WITH UNITS MATHCAD FOR FREEMany useful math and science programs are available for free or for $1. I now have all my textbooks, notebooks and reference books in PDF form and with me at all times. I only discovered this recently and previously ignored this device as a fad. The iPoD Touch is actually a great educational tool. I ended up going back to my HP28S from over 20 years ago. I have a HP49G, but don't have the patience to use it for symbolics, and can't stand the unreliable keys that are prone to generating entry errors. I was an old-time HP fan, and still am, but I'm disappointed in the latest calculators. Wow, this is impressive, and better than I get using Matlab on a PC. SYMBOLIC CALCULATOR FREE WINDOWS WITH UNITS MATHCAD FULLThe main benefit over HP and TI graphics calculators is the color display and animated real time 4D plots (3D surfaces animated like a movie) with full realtime 3d viewpoint control. It only costs about $20 and is very impressive as a graphics/symbolic calculator. I recently discovered the program for the iPoD Touch (and other such devices). Is there a program that most physicists or students use? I've been using a dry-erase greaseboard for almost all calculations, as it's one thing I can't seem to do on a keyboard at all :) It's easier to use the PC in front of you for solving compelx integrals than the calcualtor - but it's nice to have a rugged relaible one that you now how to use when you are on-site. If you are working i tend to go for a fairly simpel one with a nice keyboard rather than lots of complexity. If you are at school they may be ruleson what models you are allowed in exams. ![]() Of course it depends on what you want them for. I haven't used them but Sharp have made a comeback with a set of very cheap calculators with a 4line display that can show equations as they appear in the textbook. There are a bunch of threads here discussing the graphing calculators from HP and Casio, (both around $70-150 in stores) - they are both fantastic and offer such similar features that people are prepared to argue for hours that theirs is best. Personally I like HP I have had a simple HP scientific one for 20years (which of course they no longer make). The scientific calculators you can buy for $10 in the drug store are embarrassingly good these days. ![]()
