Multi Graphing Calculator app for iPhone and iPad

iMulti Grapher, is of the best graph applications available in the App Store, yet easy to use. it is handy tool essential for doctors, engineers, students and laboratories. Used to both derive the mathematical equation that fits a set or multiple sets of experimental data points, at any required degree, and plot them on graph, Also plot multiple mathematical equations on the same graph. It uses advanced polynomial Interpolation method to plot those data points and draw the derived equation’s curve, and uses advanced expression interpreter to plot the entered math equation’s curves. You can always manipulate the graph interactively (zooming in/out, scrolling and tracking). so you can determine the value of (y) for any given value of (x), plus the slope of the curve at that specific point. also you can get the precise numbers using a dedicated Solver UI. and now you can calculate & visualize area under curve for a given interval. you always can get the derived equations and numerical results in a formatted sheet that can be exported or shared. Minima, maxima & root points are also calculated and represented automatically.
