GraphNCalc83 App Details

GraphNCalc83 uses touch, color and blazing speed to handle your math problems. The familiar calculator keyboard, arrow keys and functions are enhanced with full touch input for all graphs, editors and menus. Enter calculations in natural textbook format. Enter fractions and view result as fractions. Trace graphs with your finger. Zoom in and out with a pinch. Explore regressions with a tap on the screen. Scroll through the list, matrix and calculation history with a swipe. Tap the ? key for help. Written using the latest 64 bit math libraries, GraphNCalc83 harnesses the amazing computing resources of the iPhone and iPad to provide a colorful, fast and fluid experience. Graphs scroll, glide and zoom smoothly. Matrix, statistics and BASIC programs run 500x times faster than traditional calculators. GraphNCalc83 includes: Algebraic entry: Enter problems using full algebraic textbook notation. The command line editor includes interactive parenthesis matching and high lighting, undo and redo, bubble function help and a 200 level calculation history and recall stack. Generate a PDF report of calculations for mailing or printing using the SEND function. Math functions: Trigonometry, logarithms, function minimum, maximum, numeric integration and derivatives, general solver, real and imaginary numbers, combination, permutation, random number generation, normal, T, chi squared, Fisher, poisson and geometric distributions, binary shift and rotate, test and logic operations, list operations including sort, std. deviation, sum, sequence, matrix determinant, transpose, sum, ref, rref, addition, multiplication. Graph functions, parametric and polar equations and statistics plots: Full color graphs with touch to trace, pinch zoom, function minimum, maximum, intersections, asymptotes and numeric integration. Output graphs in high resolution PDF format for mailing or printing. Interactively explore function behavior using variables tied to slider bars. Statistics, Inferential Statistics and Distributions: A set of inferential statistics worksheets and graphs of distributions are included. The regression analysis screen allows you to quickly compute, view and analyze a data set using a variety of curve fitting methods. Table: Analyze functions using the table viewer. Use the split screen mode to simultaneously view a graph and table. Matrix and Lists: Matrix and list editors and a full set of matrix and list operations are built in. Unit Converter and Constants: Convert between a wide variety of scientific, engineering and common units. A large set of physical constants are also included. BASIC programming: Create, edit, debug and run BASIC programs. Programs run more than 500 times faster than traditional calculators. Import and execute .83p and .8xp files. Chemistry: The calculator includes a full featured periodic table, a mass calculator and a data base of element properties. The touch interface allows you to view and interact with the periodic table to view by series, state, melting point, boiling point, electronegativity, electron affinity, valence, ionization, radius, hardness, modulus, density, conductivity, heat and year discovered. Geometry: The geometry application computes perimeter and area for a variety of 2d geometric figures including squares, rectangles, parallelograms, triangles, polygons, circles, arcs and ellipses. A full triangle solver and interactive unit circle grapher are built in. Solve line intersections, project a point to a line and find a circle given 3 points. Finance: Compute time value of money problems including annuities, lump sums and uneven cash flow analysis with IRR and NPV Built-in user guide: A user guide is included and is a touch away using the ? key or ⓘ on any menu. All functions have a full manual page with description of arguments and examples of use. Pop up bubble help displays function arguments during problem entry and program editing.

  • My favorite paid app

    This app saved me this semester. I haven’t been able to find my graphing calculator and I can’t afford to rent one, but thankfully my professor doesn’t mind me using my phone for this calculator during class.
  • Great App

    I love this app and recommend it to all my students.
  • Thanks from a blind student

    Hello, I’ve been using this app for 4(?) or possibly even 5 years now. It’s the best app I’ve ever downloaded. I don’t think I would have been able to get through Calc BC without it because I couldn’t see a regular Ti-83 well enough. If I could give it more stars, I would. Most of the time, it’s far better than Desmos. Being legally blind, and having the capabilities to do complex math is a life changer. Only thing that sorta bugs me is the splash screen and app icon because if a teacher is peaking over my shoulder they may believe me to be goofing off (happened a few times) because my original iPad Air takes forever to load it (I’ve been looking at an iPad Pro for the bigger screen but they are way too expensive. Well anyway, thanks to the developer for literally changing my life. I appreciate it.

    This is actually the calculator that schools use. The ti-84 . I love this even though it’s 5 bucks. Worth every penny.
  • Amazing!

    My TI-83 is temporarily down in action from battery acid, but after starting to use this app I haven’t even bothered cleaning it yet. Truly impressive quality control and replication of all the functions. Thank you to the developer!

    Love this App - don’t need to haul another device with me. Now has fraction mode just like a TI84
  • Great customer service. Awesome application.

    This app's developer is the best. I had a question after I purchased and he was on it in less than 2 hrs. He even comes out with improvements on occasion for free. It's awesome. This calculator is better than my ti84, and at a fraction of the cost you're getting it for a steal. If you have any need for an actual calculator unlike the bull one that comes with your phone; get this one. TL;DR This app is the best purchased app I've ever come across. A true hidden gem.
  • Great app

    The only thing I think that could complete the experience is some haptic feedback. Outside of that, it’s a very well put together app!
