![]() pdf).I've personally found the "help" mechanism in Sage quite valuable. See also Sage Documentation, where you can find tutorials, manuals, references, etc. Thin Design and lightweight with easy touchpad navigation. More details available here Wikipedia on Sage. Includes the TI-Inspire CX Student Software delivering enhanced graphing capabilities and other functionality. Graphics: Matplotlib, Tachyon3d, GD, Jmol Graphical Interface: Sage Notebook, jsmath Numerical computation: GSL, SciPy, NumPy, ATLAS Linear Algebra: ATLAS, BLAS, LAPACK, NumPy, LinBox, IML, GSL (You can also peruse sample "Worksheets" from "notebooks").Īnother "plus" about Sage Notebook is that you can create folders, save your work, etc, on-line, and can then thus access it (when on-line again) and pick up where you left off at another time.Īrbitrary Precision Arithmetic: MPIR, MPFR, MPFI, NTL, mpmathĪrithmetic Geometry: PARI/GP, NTL, mwrank, ecm Some colors are more readily available than others. You can create your own account if you scroll down to the bottom of the webpage linked immediately above. The familiar TI-84 graphing calculator was greatly improved upon with its high-resolution display and compact design. I'm not sure about its graphing capabilities though it does seem to come equipped with some graphing functionality. (see more programs listed below), and you can program, as well (Python?). I can't speak for hicalc (I've not heard of it!) but IMO, a good choice would be Sage Notebook: it integrates a whole bunch programs: GAP, R (statistics), Pari, etc. That may help you ultimately determine what works best for YOU! This article gives a recommended retail price for the calculator of 250. ![]() Sally Fischbeck, TI-92 Graphing Calculator, College Mathematics Journal, 27 3, May, 1996, pp. Various systems are listed in tables, each identifying cost, features, etc. John Berry, TEXAS TI-92, the Calculator with Symbolic Algebra and Cabri, Mathematics in School, 25 1, January 1996, pp. We sold 100,000."īy the time the HP-35 Scientific Calculator was discontinued in 1975, just three and one-half years after its introduction, more than 300,000 had been sold.Added: I found the Wikipedia article Comparison of Computer Algebra Systems from a link on Sage's site. From the keyboard and computer-menu interface to the ability to save and share work with built-in apps, the TI-Nspire CX II models retain the features and functionality that make TI-Nspire CX graphing calculators ideal for math and science from middle grades through college. Bill said "We're going to go ahead anyway." The product was so popular that HP couldn't make them fast enough.īill remembered, "We figured, in the first year, if we could sell 10,000 calculators, we'd break even. They did and determined that the HP-35 Scientific Calculator would never sell because it was too expensive. Jack Kilby, Jerry Merryman, and James Van Tassel from Texas Instruments, Incorporated (TI) created a calculator six. ![]() When the tiny powerhouse reached the prototype stage, HP asked a local market research firm to do a market study. The first handheld calculator is invented. Bil Hewlett, who, in 1968, had challenged HP engineers to make a desktop-size computer (the 9100A), challenged them again in 1971 to take that desktop computer and make it small enough to fit into his shirt pocket. Both technologies had been developed in HP Labs. The HP 35 was HP's first product that contained both integrated circuits and LEDs (light-emitting diodes). In the 1970s and 1980s, it released a variety of microprocessor-based consumer products including handheld calculators, digital watches, electronic musical instruments, and televisions. In one of the most amazing displacements in the history of technology, the HP-35 Scientific Calculator electronic calculator, and others like it, quickly replaced the faithful slide rule that had been used by generations of engineers and scientists for rapid calculation and simple computation. Casio, founded in 1946, had sold electric desk calculators since the 1960s, and introduced a transistorized form of the machine in 1965. It was the world's first handheld scientific calculator. The HP-35 Scientific Calculator, so called because it had 35 keys, was introduced in 1972. ![]()
