Newton Graphing Calculator Pro

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

Newton Graphing Calculator draws 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 plotting, you can find function root, track coordinates, pan or zoom 2D graph; draw contour, zoom or rotate 3D graph to view from all angles seamlessly by hand gesture.

Newton Graphing Calculator comes with 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 with step by step solution and live preview while inputting. Last session input is restored upon startup.

2D GRAPH
• Plot explicit function e.g. y=sin2x+2cosx
• Plot implicit function e.g. sin(x2+y)=exp(-xy)
• Plot parametric function e.g. x=sin2t/(1+t2)   y=cos2t/(1+t2)
• Plot polar function e.g. r=1+2cosθ
• Plot multiple functions e.g. f=3sint/(1+t2)   g=2cost/(1+t2)
• Plot multiple parametric function
• Support discontinuity e.g. y=tanx
• Variable name can be any symbol including Greek symbol


3D GRAPH
• Plot explicit function e.g. z=2sinx/(1+y2)
• Plot implicit function e.g. x2+y2+z2=1
• Plot contour curve of explicit function e.g. z=2sinx/(1+y2)
• Plot parametric function e.g. x=sinv cosu   y=sinv sinu   z=cosv
