Click For Summary
Several online resources allow users to input 2-variable function formulas and generate 3D graphs. Websites like quickmath.com and integrals.com offer various mathematical tools, including graphing capabilities powered by Mathematica. Livephysics.com features a 3D Function Grapher that enables users to create and embed plots in forum posts. Additionally, a utility index from Hofstra University provides a range of mathematical tools, including graphers and calculus resources. These tools are beneficial for visualizing and analyzing mathematical functions.

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.


Thanks in advance .

I saw this post in another thread by benorin:

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 - 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.

Thanks for the links.
Two of them I haven't seen before.
 

Thread 'Area of Overlapping Squares'

Here is a little puzzle from the book 100 Geometric Games by Pierre Berloquin. The side of a small square is one meter long and the side of a larger square one and a half meters long. One vertex of the large square is at the center of the small square. The side of the large square cuts two sides of the small square into one- third parts and two-thirds parts. What is the area where the squares overlap?
