Hi

Please find the attachment

It seems a singularity has been occurred at left end point for n less than unit (say n=0.5, n>0)

Is there a way to fix it?

 

n.mw

I apologize, as I'm still very new. I've flipped through a lot of pages, but I'm unsure of how Maple code translates to Maple TA.

 

I have randomly assigned an integer for the value of a year in Maple TA. I'd like it to appear as "2013" for example, but it will instead appear as "2,013". Is there a way to set the output formatting of a variable individually within a problem in TA?

Thanks!

Hello,

I would like to determine a closed form solution (=analytical solution) of the following trigonometric equations system.

TrigonometricSystem2.mw

The unknowns are :

ListAllUnknowns := [Psi(t), Theta[1](t), Theta[2](t), x[1](t), x[2](t), z[1](t), z[2](t)]

Do you have ideas so as to conduct the symbolic resolution of this trigonometric equations system ?

I have been told that the use of Grobner basis could be useful but I have never try this.

Thanks a lot for yours feedbacks.

how can active that math mode not run in maple 2016

This is a specific Maple 2016 question: I find that plots no longer remember their attributes (like size on the screen) upon re-execution of a worksheet, even though I have set the appropriate flag in the Interface pane of the preferences.

Can someone confirm this; or am I just being dense? Is this an OS X issue? An El Capitan issue?? Maple 2015 on Yosemite behaves as expected.

Maple 2016.1 on Mac OS X 10.11.5.

Thanks,

M.D.

Hi to all.

Is possible to use Maple in Excel ? How ?

Where can I search a brief description of Maple's product ?

Thanks

 

 

 

 

how to convert GeneralLinearGroup and GeneralOrthogonalGroup to permutation group for small parameters 

 

GL23 := GeneralLinearGroup(2, 3);

Generators(GL23);

i use generators , is it correct to find permutation group?

but there is a comma,

[((1, 2)(3, 5))(4, 7), (1, 3, 6)(2, 4, 8)]

does it mean that it has two different solutions?

if not, it is only one solution, 

does it mean that permutation matrix is 

permutationmatrix of  ((1, 2)(3, 5))(4, 7) + (matrix plus) permutation matrix of  (1, 3, 6)(2, 4, 8) ?

Dear All

I have 3D plot

How I can Improve this plot so that it look more aesthetic ?

Secondly, the resulotion of plot is not so good, and when I export this plot as jpeg file, quality of resolution deteriotate even more, I mean pixel tear out on zooming the image. How I fix this issue which I guess might be due to wrong way of exporting plot ?

i work on Maple 18 and recently maple standard worksheet interface not run properly.

i already have  uninstall and again i have same problems

Dear friends!

Please, suggest me, how to build a plot loocking as the following

plot

where the values on the axis X (1, 5, 10, 50, ...) are categories, not numbers?

Hi, I am a student and a recent new MapleSim user. I downloaded the MapleSim Wind Turbine Vibrations model from the Model Gallery (http://www.maplesoft.com/products/maplesim/modelgallery/detail.aspx?id=162). 

I do not understand the model diagram, and find it difficult to visualize the way all the components work. Also, how can I change the mass moment of inertia of each blade? 

This is my first question, apologies if it sounds silly. Thank you :)

I try to connect Maple with C# by using OpenMaple at http://www.mapleprimes.com/posts/38048-Using-OpenMaple-With-C

But OpenMaple just excuted in x64 mode, I want to excute OpenMaple in "Any CPU" mode. How can I do this?

P/s: I'm using Windows 7 Ultimate x64 and Visual Studio Ultimate 2013.
