Discussion Overview

The discussion revolves around using Graphmatica to create equations that represent a Christmas tree. Participants explore the capabilities of the software in relation to plotting specific shapes and points.

Discussion Character

  • Exploratory, Technical explanation, Conceptual clarification

Main Points Raised

  • One participant expresses uncertainty about how to plot a Christmas tree using Graphmatica, suggesting that any equation to achieve this may not be feasible.
  • Another participant proposes that if the shape is more important than the exact equation, plotting numerous points could create a visual representation of a Christmas tree.
  • A question is raised about the possibility of drawing lines after plotting points, indicating a desire for further manipulation of the plotted data.
  • A response clarifies that while Graphmatica can fit curves to points, the nature of a Christmas tree shape—having multiple y-values for some x-values—limits the ability to find a suitable curve, thus complicating the drawing process.

Areas of Agreement / Disagreement

Participants generally agree on the limitations of Graphmatica in plotting a Christmas tree shape, but there is no consensus on a specific method to achieve the desired outcome.

Contextual Notes

The discussion highlights limitations related to the nature of functions and how they apply to the desired shape, as well as the software's capabilities in handling non-functional relationships.

Hey does anyone know how to use graphmatica.

I need to create equations to make a christmas tree.

Welcome to Physics Forums williamsk!

I do personally have graphmatica, although I can not think of anyway to plot a Christmas tree, and I'm almost certain any relation that would draw a Christmas tree would not work in graphmatica. Sorry :( If the equation doesn't matter as much as the shape, just plot in lots and lots of points to make the tree.
 
Thanks

Is their anyway of drawing lines after you have plot the points
 
Nope, usually when you plot some points the program can get a curve to somewhat fit the points, but a christmas tree will have lots of points on a vertical line, ie some x values will have many y values. Since this means that the curve is not a function, this severly restricts our ability to find a curve to fit the data. So basically, not :( But each point is represented by a fat circle, if you plotted enough it would look like a line.
