 Hi all,

 Is there anyone who could help me with this error? I am sure there is at least one solution for the equation.

 Thanks

Maple Worksheet - Error

Typically sets are created like:

A:={a,b,c};

B:={c,q,w,e};

and then you can carryout A union B or B\A

 

what if  you wanted to create the set as

A:={values in some three dimensional space};

B:={volume, based on values taken from A};

Can these relationships be set up in Maple? If so, how? If there are commands that specifically handle these types of sets, what does maple call them?  I've seen the term 'set function' but what might Maple call them?

Note: I am not even sure i 'tagged' this correctly because it I am not sure the proper terms for these functions/sets.

Thanks in advance for any help.

I read a posting by Mr. Stephen Forrest on Thingiverse about using the exportplot command to export a 3D plot as a .stl file. I have a 3D printer and need the convert the plot from the Maple file into an .stl file.

Here is the posting I am referencing:

Thingiverse/3dmodelimportexport.pdf

I was able to follow the commands successfully in the referenced paper for a hyperboloid or revolution that I plotted in Maple - it was very helpful. However, I could not figure out how to access the temporary .stl file that was created so that I could open it using my 3D printer's software.

My question is: Once I execute the "exportplot(stl, hyprev)" command that I inputted, how can I find the file in the Temporary Directory in order to open it from the software I use for my 3D printer?

I would appreciate any further details you can provide for accessing the temporary .stl file I created in order to be able to print the object.

Thank you!

I wote a command that creates a plot with a single point:

plots[pointplot](a*[1, 1])

Before hitting Enter I called the context menu and chose Explore. As I change the parameter a the point remains fixed in the picture but the scales change. I wanted the opposite: the scales should stay fixed and the point should move. How can I do this using Explore or in some other way? I would like to see the point move as I drag a slider control.

Thanks for the help.

 

hi every one , i have a problem with integration,which one is correct !? also when i remove epsilon option, it returns unevaluated integral . can i have crorrect and reliable answer?

If you try and scroll a page up or down, it just selects the content.  How hard would it be to fix this?

I use Maple on a Surface Pro 4 tablet and the math input panel does not work with Maple.  This would be a great feature to have.  Or does anybody know how to get it working?

Why can't I sub both values at the same time and/or why does k stay symbolic but not d?

how i tackle an bvp ode,derivative involve in bcs.i want to solve by dsolve comand or by using Rk meethod.i am attaching the maple sheet,ode wrrten in attached maple sheet

Hello awesome maple people

I have the following Matrix

R := Matrix([[1, -2, 2, 6, -6], [2, -3, 4, 9, -8]])

then i do

ReducedRowEchelonForm(R);

and i get an output, but is there any way to get it to give me the output in Parametric form?

Like this https://snag.gy/BQniuR.jpg

Thanks in advance :)

I created a new Document with a single command:

A=1

Then I right-clicked on the command and chose Explore from the context menu and then clicked on the Explore button in the dialog box. A rectangle with a slider appeared. So far so good.  However, I cannot delete the rectangle from my Document. I tried to select the rectangle and press Delete, Ctrl+Delete, and to right-click on it and choose Cut from the menu. Nothing works.

If I select both the rectangle and the command A=1 all the three actions described above also fail to delete anything.

Help will be appreciated.

Using Maple 2016, I created a new Document with one line:

A=(1,2,3)

Right-clicking on this expression I thought I could choose Assign to a Name, as is done in Clickable Calculus Series - Part 3: Multivariate Calculus, found here:

https://www.youtube.com/watch?v=GYN-GetHRFA

However, Assign to a Name does not appear in the context menu.

On the other hand, if I write

B=1,2,3

(with no parentheses) and right-click on this expression then Assign to a Name does appear in the context menu.

Any insights on this?

Thanks.
