I want to graph the portion of the plane 2x + 3y + z = 6 that are located in the first octant of a xyz coordinate system. The following implicitplot3d should in principle do it:
When I execute the command I actually see the expected triangular part of the plane for a split second, but then it disappears. I can of course solve the equation with respect to z and use plot3d, which works fine. The problem is that I want to use implicitplot3d to illustrate the concept of implicit surfaces to the students that I am teaching. So for pedagogical I want to keep the Maple code as close as possible to the way that the problem is stated in the text book. What I mean is that I am not looking for technical workarounds that tend to move the focus away from the core mathematics.
