How can we help?

You've used all your votes and won't be able to post a new idea, but you can still search and comment on existing ideas.

There are two ways to get more votes:

  • When an admin closes an idea you've voted on, you'll get your votes back from that idea.
  • You can remove your votes from an open idea you support.
  • To see ideas you have already voted on, select the "My feedback" filter and select "My open ideas".

  3. How do I enter circle equations in a Function Definition?

    I am trying to use Function Definitions to enter a circle eg (x – a)^2 + (y – b)^2 = r^2 so that I can then use the constant controller to vary a, b and r. How do I do this? If I enter the above equation I get the wrong graph. If I try to re-arrange the equation to get it in terms of y then I get a square root involved and then I only get half of the circle shown (as the positive sqrt solution only is used). Also there doesn't seem to be an equation editor…
