Functions 3D Plotter is an on line app to plotting two-variabled real functions, ie functions of type f(x,y) or with more precision

f: R2 → R
  (x,y) → f(x,y)

3D Functions Plotter calculates double integrals in analytic or numeric form.

3D Functions Plotter also calculates partial derivatives (analytics) ∂ f/∂ x, ∂ f/∂ y.

Inputs

Simply enter the items:

1) xMin: Minimum value of x

2) xMax: Maximum value of x

3) yMin: Minimum value of y

4) yMax: Maximum value of y

5) Function: the function of xy variables, for example x^2-y^2 ó e^(-x+y), etc ...

Outputs

To begin the calculations simply click "Show Graph": After a few seconds, a window will open with the graph of the function in the intervals introduced

To calculate double integral simply by clicking "Double integration Tool" and a form with double integrating tool will be shown.

Final comments

Functions 3D Plotter does not require installation of any kind, just a browser with javascript support
