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.

  • Very helpful

    By BetaAlphaY
    So close to the TI calculator, I only need my device most of the time.
  • Good

    By RKVARes
    My teacher recommended me get this app but when I heard it was 5.99 I was like wow it’s overpriced but yeah it’s overpriced but it’s pretty good
  • Don’t spend your money on this

    By idifkcbchk
    I got this app purely so I could do math homework since my calculator wasn’t working, so I download the app and nothing works. The UI is absolutely horrendous, and the whole thing doesn’t work. I tried for hours to get this app to work, but it just doesn’t. It’s just horrible. Do not, under any circumstances, but this app.
  • Wow! Faster than my TI-84 Plus CE

    By smash68
    This app does everything my TI-84 does a hundred times faster with more colors and way better resolution. Graphs draw with LABELED axis markers and you can instantly find intersections just by dragging your finger over the intersection point. It worked perfectly for my stats class last quarter and this new update is even better! I LOVE the new font size arrow keys and the math typesetting and the shading on the display makes it super easy to find your result. Thanks developer for another great free update👏👏👏
  • Loved

    By Treesdanceinthebreeze
    I have had this app since 2014. I bought it because the stats class I was in needed a specific function on a graphing calculator but I didn’t want to buy a brand new calculator. This has been my go-to calculator since. The only issue I have and it’s more pet peeve than anything, is that when you calculate a number and it won’t be a whole number the answer comes out as a fraction and then you have to punch in a few numbers to get a decimal. It’s annoying but other than that the calculator works just like a normal one for less money.
  • Well Worth the Money!

    By hilltrekker
    I am a high school mathematic teacher. I have tried many app calculators and this is the best second only to the TI nSpire CAS app. This one however is very intuitive and if you are used to the TI 83 or 84, this calculator will seem very familiar and has more features than the handheld calculators. I highly recommend it!
  • Great Calculator

    By Magnolia0160
    Works just like my TI-84!!! Love it!!!
  • Amazing app

    By broken hearted z
    I have been using this app for chemistry, physics, and calculus. It’s a game changer when it comes to graphing since it’s touch screen.
  • Fantastic App!

    By Magic0101023
    Thank you so much for this, I can imagine how useful this will be for me in the future for my college years! The reason why I bought this is so I am able to help my friends out much more effectively when I am not at home (meaning I don’t have access to a calculator to check). I absolutely love this also because of the button layout and everything is exactly like my TI-84 Plus CE so I am able to use this to its full potential. Please keep this fantastic app running, you (the developer Ernest Brock) are amazing to say the least.
  • Amazing!

    By Sky landers C.P.
    I love it. It has all the functions of an $80 calculator for 1/10 of the cost. Would definitely recommend!
