Functions 2d

by Benjamin Joffe ·

Draw 2D curves from mathematical expressions

Description

Enter a mathematical function and have it plotted on a 2D plane. ------ Equations are entered as a function of x. An example for a unit circle would be: f(x) = (1-x^2)^(1/2) For a full list of the functions, operators, variables and constants available in this widget visit http://functions2d.abrahamjoffe.com.au/v0.1.html There is one main feature that is missing from this release and that is that the axis do not have markings on them. This is due to the limitation of Canvas not being able to write text, however in a later release I will have my own text implementation. Enjoy!

    it's wonderful
  • yhtlyonSep 6, 2006
    Great. Use the drawing color when displaying the text of the equation (ie (1-x^2)^(1/2)).

    Being a Calculus student, I now love this widget. When I'm doing my online homework it's great to have one less thing on my desk (my old TI-85) for quick simple verification of my graphs. It would be nice to have the ability to trace the graph to get f(x) at a given x coordinate.

    It is very great, thx

    Impressive!

    This is great! So much better than those boring TI-85 calculators... How about adding an "equal to or greater/less than" (and so forth) feature?

    wangjiaji: if Microsoft Office was a widget i would rate it negative 30.

    Is there a way to copy and paste the graphs into a word doc? I'd absolutely love it if there was a way to do so!!!

    Please in new version add modules! Thank you

    stilltrusting: There is a 'save' button which will save the image as a plain png, this can easily be copied and pasted into word.

    Hi! I loved this widget... actually helped me. I wish if you can introduce a hack to know at what what area the different functions share in common and the points at which the functions meet on the graph. That would really make the Widget actually helpful! Just wanted to help! Thanks a lot for the widget. You might not know how much it helped! Good luck!

    Nice and usefull widget .
  • Petr047Jun 8, 2009
    Thanks for the widget. It works pretty well except the negative numbers with even exponent.
  • Petr047Jun 8, 2009
    Oh sorry, I forgot brackets.

    this does not for me the correct form of sin(x) ... http://img4.imageshack.us/img4/1083/sinx.png

    This is just great.... If there were grids for the graph, it would be better.

    Clicking on the disk icon to save as image, does nothing at all. Seems broken.
