Graphing Calculator + Symbolic Math

Why this app?
We believe that symbolic math or graphing calculator should be as intuitive as handwriting, without overhead in user input and complex syntax. For example, normally we write "sin2x" on paper in math class, but input "sin(2*x)" in a calculator. Wouldn't it be wonderful to just input "sin2x"?

Newton Graphing Calculator graph 2D curve and 3D surface by math input like handwriting. With our innovative parser, math syntax is as simple as when you write it on your note. 2D or 3D graph is recognized automatically by number of unknown variables, through our powerful symbolic math engine. After graphing, you can find function roots, track coordinates, pan or zoom 2D graph; draw contour, zoom or rotate 3D graph to view from all angles seamlessly by hand gesture, to study mathematical property of the function.

Newton Graphing Calculator comes with transparent graph, optimized keyboard, axis label, function legend, color picker and formatted math formula ready for productive use. Resulting graph and math formula can be sent by email to put into homework, shared with friend on Facebook, Line or Google+.

Newton Graphing Calculator features numerical calculator and equation solver with step by step solution (Pro version only), and live preview while inputting. Favorite input can be stored in your math collection to save input time.
