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.
Okay, it has arrived. A very decent TI-83 clone for the iOS. Looks to be very close to key-for-key to the actual hand held device. Many thoughtful enhancements to the UI, particularly in graphing. Everything I expect to be there in Stats looks to be there. I was particularly happy to see this app play nicely with other apps, like my drawing app, for multitasking. I can show, draw, calculate, all at once and that is so nice. Whoever wrote this app: A+.
You obviously can’t use this app in place of a calculator on exams, but for homework and studying it’s a great tool!
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!
This is actually the calculator that schools use. The ti-84 . I love this even though it’s 5 bucks. Worth every penny.
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 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.
