Graphing calculator for iPhone & iPad
Calc84 gives you the familiar keypad of a classic graphing calculator, plus a computer algebra system, an equation solver and complete statistics.
Features
Graph functions, solve equations, simplify expressions and run statistics, with answers shown the way you would write them.
Plot function, polar and parametric graphs, then trace them interactively or step through points by hand.
A built-in computer algebra system simplifies, differentiates and integrates symbolically. Complex numbers, matrices, vectors and your own functions are all there too.
Auto Solver gives exact, symbolic roots. It handles polynomials up to degree five and systems of equations with up to 5 variables.
Run 1-Var and 2-Var statistics, fit seven regression models, and use every common hypothesis test, confidence interval and distribution.
Tests and intervals
Distributions
Math OCR reads handwritten or printed math from your camera or your photos, and turns it into an editable expression you can work with.
Decimal, fraction, mixed fraction, repeating decimal, degrees-minutes-seconds and polar form, plus prime factors, divisors and Roman numerals.

Familiar by design
The keypad works the way you learned it in class, so there is nothing new to figure out.
Choose Graph mode with MODE, enter your functions in the Y= editor, then press GRAPH.
ALPHA then ENTER brings up the SOLVER menu, with Auto Solver and dedicated polynomial and system solvers.
TABLE lists values for the selected graph, and CALC finds its min, max, d/dx and integral.
