Just a quick question again: if I create a function by way of, say: f := x->2x; then I can't use the plot builder by right-clicking the result. However, defining an expression as f := 2x; works fine. I realize that the plot builder pulls in the function literally and it doesn't like the format of x->2x. However, I'm just finishing up a student manual, and since it is a tad bit confusing, I just wanted to make sure that this is the intended behaviour, and that I'm not missing anything.
Well, that last blog entry sure generated a lot of discussion! I'm going to move on to something a bit more fun and less controversial: how to generate a 3-D plot of a polyhedron.
There are different ways to do this in Maple, depending on how complicated the polyhedron is and what else you want to do with it. I've uploaded a worksheet with a few simple examples.

Can Maple produce plots of data with error bars ?
When I post a question, at the top of the screen it says I get one point. What is that for?
I am trying to do some calculations using very small numbers. For example evaluating (sqrt(x^2+9)-3)/x^2 for x=.1, .01, .001, .0001, .00001, .000001 and .0000001 which should result in values closer and closer to 1/6, but the calculations seem to break down for any x value smaller than .001 which surprizes me. Does Maple offer some sort of double or triple precision option that I can use to accurately do calculations with the smaller numbers?
Could some one help me to plot this population balance equation ?

Hi. I'm currently running Maple 10 for my project. So far I have successfully plotted 2d graphs of Re(A) vs d and Im(A) vs d. Both Re(A) and Im(A) are dependent on d.
Now what I want to do is to plot a 3d graph with Re(A) in the x-axis and Im(A) in the y-axis with an independent variable of d. I can't seem to figure out how to do this with the Interactive Plot Builder and I wish I could try solving the problem by posting in this forum.
I just started using Maple so any tip would be very much appreciated.
I've been asked: how do I include a mathematical expression in a plot caption without having it evaluate? An example is displaying 2(x+y) in the caption without having it appear as 2x+2y.
The easiest way to do this is to create an atomic identifier from the expression in the input line. In the 2-D input line, you'll have plot(..., caption=2(x+y)). Select 2(x+y) and right-click to bring up the context menu. Then go to 2-D Math -> Convert To -> Atomic Identifier. This turns the expression into a single name. Note that it is no longer equivalent to the expression 2(x+y), even though it looks exactly like it.
Even though dsolve is great, I'm just curious as to how the "Add an initial condition" menu choice works in the Standard Mode.
If I enter a simple equation like this:
I would like to create the initial condition that y(0)=6. I right-click, add an initial condition and blue "reply" text comes up that looks like the IC I would enter for dsolve. However, I can't edit that IC, and it just generally does nothing. How would I go about this?
I have some 2-dimensional data to which I would like to fit a curve. The data is not functional, i.e. there can be multiple values of y for a given x. The curve should be continuous, but otherwise I have little idea about what form it should take.
Maple provides a really nice way to plot one such curve: Statistics[ScatterPlot] with the lowess option. But I do not want to just plot the curve. I would also like to do computations with the curve. For example, I would like to compute the sum of squared residuals.
What is the best way to get the curve (as a procedure, say)?
Does anyone else see the following strange behaviour in the Maple 11 plot engine?
I was acting in a Std GUI Worksheet, not a Document. (I use Maple for 64bit Linux, which may or may not matter.)
1) In this next plot below, a (superfluous?) solid triangle appears. It lies in a xz-parallel plane at y=-1, with vertices (0.0,0.0,0.0), (1.0,-1.0,0.4), and (1.0,-1.0,0.0).
I´ve just programed some procedures. Those procedures don´t have any syntax errors. But after the execution I don´t obtain any result, I get only the instruction to execute. Where´s the problem?
I am trying to plot a graph of 3sin(3x) that is being displayed as choppy lines. How do I get it to display smoother?
Can anyone point me to a tutorial or something to show me how to take 2 curves and rotate them around an axis to form a 3D solid?
I'm trying to set my default font and type set for my documents and worksheets but can't find where to do so. Using Mac OS and Maple 11. If I turn off bold for example and hit return it turns it back on. Even tried selecting entire document content and turning bold off but still when I hit enter it goes back to bold. What gives?
