3D Functions Plotter

Functions 3D Plotter is a support tool designed to represent graphs of functions of two variables, ie functions of the form

f: R2 → R
  (x,y) → f(x,y)



Functions 3D Plotter calculates the double integral in analytical and numerical formats, this last being in approximate mode.

Variables

Use x and y vars only, other variables are not supported, for exemple if you enter
f(x,y): x^2 + t^2
an error message will be shown, the correct way is
f(x,y): x^2 +x^2

Examples and functions notation

These constants are supported

Constant	Value
pi	3.14159...
e	2.71828...
1e-3	0.001
2/3	0.666...

All Mathstools apps support a large number of of functions, examples are

Function	Description
abs(x)	absolute value of x
e^(-x)	exponential of -x
log(x^2+1)	Natural logarithmic of x^2+1
tan(x)	tangent of x
sqrt(x+1)	square root of x+1
arcsin(x+1)	arco sine of (x+1)
cosec(x)	cosecant of x
(x^2+1)/(x^3+2)	Polynomic division
cosh(x)	Hyperbolic cosine of x
If in doubt, always use parentheses, for example to represent the function use 1/(sin(2*x))

Note that

Some calculations uses numerical methods (as in this case the definite integral) that means that these calculations are subject to two kind of errors

1)Truncation mehod error

2)Error due to limitation of computer arithmetic

Use 3DFunctions responsibly as a support tool and as suggestion. Learning mathematics is only practicing, therefore, the calculations must be made by the student.
