Graphing Calculator
What this actually does
Every button, label, and menu is laid out exactly like the graphing calculator most math classes use — 2nd, ALPHA, Y=, WINDOW, ZOOM, TRACE, GRAPH, all in the usual spots — so a lesson written for the real thing still works here, keystroke for keystroke. Tap the tab docked to the left edge of the screen for controls that change how it looks and fits, without ever changing how it works. Handy for algebra, precalculus, and AP Calculus or AP Statistics homework, and for SAT, ACT, and PSAT practice — anywhere you'd normally reach for a graphing calculator.

It isn't affiliated with, endorsed by, or sponsored by any calculator manufacturer, and standardized tests that require a specific physical calculator still require that physical calculator — this is a homework and practice companion, not a substitute for one.
