Function evaluation tool

  1. Oct 30, 2006 #1
    Here is the latest addition to online physics tools. So far I had discuss about the 2D and 3D graphing tool and thanks for all the people post comments and ideas about it.

    This latest online function evaluation tool will generate data table dynamically for f(x), f(x,y) functions

    Function can be simply entered like this

    where x[-5,5,1] is the range
    X min = -5
    X Max = 5
    X step size = 1

    Here are two example calculation from this tool

    It would be far more useful to start learning Mathematica. All these 'tools' in one smart package. :smile:

    But some time it will be useful to have a free tool online, people can easily make reference when they doing online discussion via forums ..etc. so every one will have free access. And also every one does not have Mathematica. Mathematica is not free …..

    I know - I was just a bit idealistic. :smile:
