# Online 3D Graph View of 2-Variable Functions

• tehno
In summary, the conversation is about finding links for online 3D graphing of 2-variable function formulae. The person mentioned websites that have online calculators for algebra, solving equations/inequalities, derivatives, integrals, and matrix arithmetic. They also mentioned a website that allows for embedding customized plot graphics into forum posts. Another website was mentioned that includes various categories of math utilities/tools. The person expressing gratitude for the provided links.

Hello:

Anybody knows good links where one can insert
2-variable function formulae and get online 3D graph view of the surfaces?
Just curious if someone made (Java prefered) program of this kind.

Here are a few websites that have online calculators:

www.quickmath.com - powered by webMathematica: this site is very handy and will do algebra (factoring, simplify, partial fraction decomposition, expand), solve equations/inequalities (single or a system), plot equations/inequalities (single or a system), derivatives, definite or indefinite integrals, and do matrix arithmetic/inverses/determinants.

www.integrals.com - powered by the Mathematica engine: just what it seems, but it will only do indefinite integrals.

www.livephysics.com - has these tools: Evaluate Function, Function Grapher, 3D Function Grapher. Very nice since the 3D Function Grapher allows for you to plot a 3D function and then cut and paste customized UBB code from the page into a forum post to embed the plot graphic you made into your post (see add).

http://people.hofstra.edu/faculty/Stefan_Waner/RealWorld/utilsindex.html [Broken] - includes these categories of utilities/tools: Graphers, Regression Tools, Matrix and Linear Algebra Tools, Probability and Statistics Tools, Calculus Tools, Math of Finance Tools, and Miscellaneous.
