I have seven curves (expressions) R:=f(x) for different value A.

1. How to Plot all curves on one 3D spece plot?
2. Hot to get (fit) surface equation R:=f(x,A) from all 2D curve? 



the question is 

Consider the function φ(x, n) defined as



Define a functional operator “phi” in order to evaluate φ(x, n) when we enter the command phi(x,n);.

Use Maple to draw a surface plot of this function for x ∈ [0,20] and n ∈ [1,20]. Your plot should have axes displayed and be fully labelled and titled.

Hello, can you help me? I need to draw a simple model of solar system (9 planets around the sun). I tried to draw planets with

> a[1] := animate(implicitplot3d,



I tried this, but it doesn't seem to like having the x's and y's in the z range. 

 implicitplot3d(x = 6, x = 1 .. 7, y = 2 .. 5, z = 0 .. (1/4)*(x-4)^2+(1/5)*(y-3)^2+10
  , view = [0 .. 8, 0 .. 8, 0 .. 20], transparency = .5, style = hidden);
Error, (in plots/iplot3d/implicit3d) bad range arguments x = 1 .. 7, y = 2 .. 5, z = 0 .. (1/4)*(x-4)^2+(1/5)*(y-3)^2+10

I'm trying to plot a surface above the xy plane that looks like a solid,...

How can I make the 3d plot of a function such as z = 4x^2 - y^2 so that only the part of the surface above the unit circle in the xy plane is shown?


I am creating a maple document to display the tangent plane to a function. the resulting function and tangent plane are displayed in a plot component. The problem I am having is that I can display both the function and the tangent plant at the same time with the foloowing statements:

PlotSurfs := plot3d([Func,TanPln], x = Xo-DmX .. Xo+DmX, y = Yo-DmY .. Yo+DmY,axes=VarAxes,scaling=VarScl,orientation=[OrX,OrY,OrZ]);

 DocumentTools[SetProperty](PlotWin, value, PlotSurfs);

How would you transform a 3D plot structure into a 2D plot structure? I have in mind 1) creating a 3D plot with odeplot or with plot3d, 2) selecting (say) 4 orientations, 3) transforming each into a 2D plot, 4) exporting the 2D plots using the Standard GUI.

The reason behind my question is that the best-looking exported plots that I have been able to obtain with Maple are 2D plots exported as postscript with the Standard GUI. 3D plots don't look nearly as good when...

I was digging through my old worksheets and came across something I created for one of my projects I never finished or well am still intending to work on.  Anyways I had come across a plot created in Matlab and noticed Maple didn't have an option to create gridlines in the axis on a 3d plot like Matlab did (at least I think it was Matlab) in any case I tried to mimic the same thing in Maple as exactly as I could.  The below is the groundwork I came up with and I...

It would be good I hope to present symbolic-numeric CAE system for framed structures analysis.

It will be available soon as Preview version for enthusiasts

The main features are:

  • One calculation act - all analytical dependencies.
  • Fast designing process for structural systems in industry, consulting and design companies;
  • Fastest parametric analysis of construction. New quality of designing in optimization tasks,...

Is there a way to make the x, y and z axes thicker in 3d plots?

Hi! I need some help with a curve I'm trying to plot.

f(x,y)= x^2*y^2/(x^4+y^4)

I'm asked to intersect the surface produced by f(x,y) with the plane z=1/4 and to plot the curve generated by the intersection (in 3D). I found how the curve looks like but I don´t know how to plot that in 3D.

I need to create an ellipse and an ellipsoid (ellipse in 3D) through code. How would I be able to do this? Can someone please give me an example for each?


Also, I will need to create a line for an ellipse and a plane for an ellipsoid that intersect. Would I be able to find the intersecting points? Would I be able to find the function for the curve line that is created when a plane intersects an ellipsoid? Also, how would I find the surface area and volume...

I'm looking for information on the x3d format, with a view to converting x3d to 3d-pdf.

  1. x3d formats are available from standard gui by right-clicking to "export".  How can you use plotsetup to access the "Extensible 3D" format with a line of code?
  2. what x3d viewer do you recommend?
  3. do you have any tips on converting x3d to pdf?

Let me elaborate to provide context to my questions. In a previous post (
