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. John Berry, “TEXAS TI-92, the Calculator with Symbolic Algebra and Cabri,” Mathematics in School, 25 #1, January 1996, pp. “The slide rule looks more ancient than ever.” Keywords: CORDIC Structure, Transcendental mathematical functions, Angle convergence, Angle Precision, Scientific calculator, Digital Signal processing and. New TI-92 at the border between a calculator and a computer. “What’s in a Name?,” Washington Post, July 10, 1995, p. This TI-92 was owned by Harvard University mathematician Andrew Gleason. The TI-92 incorporated the symbolic algebra software DERIVE and the geometry package CABRI. There is also a backup battery of style CR2032. Moving a lever on the top edge makes it possible to change the four AA batteries. Display expressions in proper notation Visualize and edit complex expressions. There is a connection for a cord, but no cord.Ī mark on the back reads: TEXAS (/) INSTRUMENTS (/) V0116515 I-0995 (/) MADE IN TAIWAN R.O.C. Calculate with precision Solve equations symbolically factor and expand variable expressions complete the square and find anti-derivatives, computer limits and exact solutions in irrational forms on a powerful CAS platform. It is possible to split the display, showing, for example, functions on one side and their graphs on the other. For example, pushing the F2 function key brings up such “algebra” commands as solve, factor, expand, zeroes, approximation, common denominator, proper fraction, trigonometry, complex, and extract. These function keys operate a toolbar on the screen that brings up pull-down menus on the screen. The display is above the alphabetic keyboard and function keys are on both sides of it. An alphabetic (qwerty) keyboard is on the bottom left, and a numeric keyboard like that of an ordinary electronic calculator is on the right. pdf).I've personally found the "help" mechanism in Sage quite valuable.This programmable, handheld, symbolic graphing electronic calculator has a black plastic case and cover. See also Sage Documentation, where you can find tutorials, manuals, references, etc. More details available here Wikipedia on Sage. Some graphing calculators have a computer algebra system (CAS), which means that they are capable of producing symbolic results. 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 Other great apps like Symbolic Calculator are fxSolver, Photomath, Symbolab Math Solver and Microsoft Math Solver. The best alternative is Wolfram Alpha, which is free. (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 There are more than 10 alternatives to Symbolic Calculator for a variety of platforms, including Android, iPhone, Online / Web-based, iPad and Android Tablet. You can open multiple calculators at the same time in resizable windows on the desktop and switch between Standard, Scientific, Programmer, Date calculation, and Converter modes. You can create your own account if you scroll down to the bottom of the webpage linked immediately above. The Calculator app for Windows 10 is a touch-friendly version of the desktop calculator in previous versions of Windows. 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! Various systems are listed in tables, each identifying cost, features, etc. Added: I found the Wikipedia article Comparison of Computer Algebra Systems from a link on Sage's site.
