Dear all,

I would like to find a way to make the reflection of a spherical wave inside a tube (a cylinder). You have herafter an exemple of a sphere increasing inside a tube, but without the reflections...


Any idea how to do this?

Thanks a lot for your help.


Hi all,


I am generating a sphere with increasing radius that interacts at some point with a plan, just like this:

I would like to find a way to make the sphere "wave" (I agree this is not a wave...) reflected by the plan as in a mirror.

How could I do that ?

Thanks a lot for your help.


I am having trouble to display a 3d and a 2d plots in a same figure. I tried with the display command but no luck.







To combine both I used display


I ends up with a structure error

The second question is how to plot f(x,y,z)=exp(x+y+z)?


Is there an elegant way to plot in 3d only the portion of the function f(x,y)=sqrt(25-x^2-y^2) for which 9 <= x^2+y^2 <= 16 ? I'm looking for a nice plot that shows it against the whole sphere with radius 5, so that it's clear which part of the sphere is cut out.

Hi all,

I have three points in 3d space say A1=[a11, a12, a13]; A2=[a21, a22, a23] and A3=[a31, a32, a33]. I want to fill the triangle formed by these points. How can I do that?

Thanks is advance.

Hi all,

I have a 3D graph and when I right click on the surface, under style, I can see the option of contour. When I click on that I can see some contour associated with the surface. I want maple to show the values for each contour when I observe it from the top . I want to copy and paste some surfaces in a same figure and campare the contours.


Thank you




I try to draw together point (0,0,12) and the line  x=4t, y=-2t, z=2t on one graph 3D. Somebody has some pointers? Thank you 

A quick question, Can I add legends to 3D plots? 


I have studied most posts about plot quality, still confused.


When I export 2d graphs and import the to microsoft word, the quality is horrible. How can I presents my results in a reseanably good way? 

what command should I add to my code that the quality increase notoceably? 

Any suggestion about 3d plots? 

If I export as an eps file, how can I import that in microsoft word? I did, but I guess they are not compatibble. 


thank you 



I am trying to find the interpolation of a 3D function.

I have the vector x, the vector y and a matrix M at my disposition.
I know how to do the pointplot3d , but I can not find the function: f(x,y) 

any suggestion?


Thank you for help

Hi all


How can I make maple to write the values of each contour plot on the graph?

I have a 3d graph and want to have a contour plot in which each line have the associated value on it. I know I can use legends and input the values for each line by hand but I dont know those values. I just need maple to calculate the values and write them on the contour plot. 


Many thanks for helping me 


I am trying to plot 3d scattered data as a 2d scatterplot with the third dimension being displayed as colour or a line that separates the value of the two functions (for example, the higher value and lower value at that point). I attached the file. I have two functions and several parameters that are constant. Here, I want to use P[A] on the x-axis, and P[B] on the y-axis. The z dimension is the profit functions, either Profit[1] or Profit [2]. I want to show them in colors like the highest one is red and the lower one is green, or something similar.  P[A] and P[B] are probability values and P[B] is between 0 to 0.50 with 0.01 increments, while P[A] is always less than P[B]. The file is here:


P[A] := 0 ..P[B]-0.01

P[B] := 0 ..0.50

Anyone please help me to code this problem.Thanks,


Suppose that we have the following curve on a unit sphere




which is the implicit equation of a circle in "cylindrical coorinates" (r,phi,z) on the sphere.

How can I plot this curve without solving the implicit equation for r or z ?

Also, I don't want to make any parameterization.

In this paper we will demonstrate the importance of using simple to complex algorithms applied to complex systems in civil and mechanical engineering. In order to develop solutions that developers need to be involved in issues of advanced dynamic computer science. We show how is that with the Maple scientific program and through component-based algorithms can generate power then then be inserted into specific algorithms. Will form patterns with movements of rotation and revolution of their axes, in each case to model and analyze the curves thereof comprising. With these modelalos and curve analysis we can predict manufacturing costs, freight, inter alia estrcturas which they can be used with the correct use of Maplesoft.

hello guys,


i have a system of autonomous equations which i want to plot its 3D phase space with directional field,

i have some problem with it , and i dont know how to command for add some directional field for 3D phase space .


thank you guys
