3D Function Grapher

Plot an f(x,y) style function like x^2-y^2

images/grid3d.js

Press "Edit" and try these:

x^2-y^2
-5*x*y*e^(-x^2-y^2)
(sin(4*x)-cos(5*y))/5
cos(abs(x)+abs(y))
abs(x)-abs(y)
(x^2+y^2)^0.5
cos(x^2+y^2-0.5)-0.5

You can change "xMin", "xMax", "yMin" and "yMax" values, but at this stage the program is always centered on 0.

The "xN" and "yN" control how many squares are plotted, go too low and it gets too chunky, go too high and the program really slows down and uses up a lot of your devices resources!

Also try changing the "zFact" to make the z-height more or less dramatic.

All Functions

Operators

	+	Addition operator
	-	Subtraction operator
	*	Multiplication operator
	/	Division operator
	^	Exponent (Power) operator

Functions

	sqrt	Square Root of a value or expression.
	sin	sine of a value or expression
	cos	cosine of a value or expression
	tan	tangent of a value or expression
	asin	inverse sine (arcsine) of a value or expression
	acos	inverse cosine (arccos) of a value or expression
	atan	inverse tangent (arctangent) of a value or expression
	sinh	Hyperbolic sine (sinh) of a value or expression
	cosh	Hyperbolic cosine (cosh) of a value or expression
