This can't always be done in general, and even if it can it's usually really ugly. For example, sin(sin(y) + y) = x^5 - x + 1. There are other algorithms to do this kind of implicit plotting. On Apr 23, 2007, at 11:25 AM, Timothy Clemans wrote: > > Do we just create a function based on the eq

Do we just create a function based on the equation in question or in the case of the equation of circles two functions and just plot the function(s)? On 4/23/07, Bobby Moretti <[EMAIL PROTECTED]> wrote: > In terms of features, something comparable to Apple's grapher application > would be nice. S

In terms of features, something comparable to Apple's grapher application would be nice. Specifically, if you give, say, a polynomial in two variables, it should automagically do implicit plotting. I think that having dead simple implicit plotting could be a huge selling point for SAGE. ~Bobby On
