I'm from Vietnamese. My English is not very good :D I have a question about tubeplot in maple. Can you give me a form of tubeplot? I read it in the MapleHelp, but I don't really understand. Example:

y:=x^2+x-1. tubeplot y. create a plot, limit by y, x=1,y=5,around Oy .

Can you hepl me? Thanhks you so much!

I have a problem, to which I think the solution is to make ln(x) inert.  I'd like to be able to enter the following

diff(1.5^x,x);

and get back 

ln(1.5)1.5^x

But of course Maple returns 

It seems to me that if I could make ln(x) inert for that might work, but I don't really know much about the ToInert command.  Or maybe this isn't the right approach.  

Hi

Please help me to solve EQ in attached file.

I need amount of P.

Is there a command in Maple that directly divides one equation by another and produce the result as one equation directly? I wanted to verify the text book, where it says

      x^2-y^2 = a*z^2   ----- (1)
      x-y          = a*z       ------(2)
dividing (1) by (2) gives

      x+y = z  ---(3)

So I typed this in Maple:

restart;
eq1:=x^2-y^2=a*z^2;
eq2:=x-y=a*z;

But now what to do? I can see the answer in book is correct by doing

   solve( {eq1,eq2}, {x,y} );

And adding the solution given above, which shows it is z indeed.  But I'd like to get Maple to generate equation (3) above automatically.  Is this possible?

I was looking for help on polynomial division using Maple via google. But I am having hard time deciphering this web page on quo command. Is this syntax supposed to work on some Maple version?

http://www.maplesoft.com/support/help/Maple/view.aspx?path=Task/QuoAndRemOfPolynomialDivision

I also do not understand how the polynomial and the divisor are "entered" without it being assigned to variables like this. I thought it was the browser, but  I tried both Chrome and Firefox and they both show the same page.

Is the above using some new Maple product? I am using Maple 2015 on windows and I get an errors trying to type the above on my Maple worksheet.

Hey.

I just got this document and can't seem to open it as a .mv file - I tried to attatch it here, but it wouldn't let me for some reason, so I saved it as a .txt and attatched it instead. Is my file broken, and if so, is there any sort of tool to fix it?

Thanks

Let x and y be 4-digit integers such that the last digit of x is 7 and the last digit of y is 1. That is, x = abc7 and y = rst1, where a,b,c,r,s,t all run from 0 to 9. There are 1000 possibilities for x and  1000 for y. What are all possible products x*y? I would like all possible products listed in increasing order. The first element of the list should be 7*1 = 7 (since 0007*0001 = 7). The last should be 9997*9991 = 99880027. Thank you! 

hi all

i have a plot in maple. how can i print the maximum point of my plote?

hi friends

i have a question and i could find the answer in existing questions but it was not clear at all!!!

i want to label my contours and i know that i should use lebelledcontourplot command.

But how?!
i could find an answer:

"1- First download the files located on his webpage.  Advisor6.zip    It should be zipped with 3 files in it. 

2 - Unzip them and copy them into a directory which you name, probably somewhere in the maple directory named advisor.  c:\maple12\advisor

3 - Then create a maple.ini in the maple12 directory with the following line to match your directory location  
libname:= `c:/maple12/advisor`, libname:  just like on the instruction installation page."

these are my questions:

1-how can i create a maple.ini?!
2-what should i do with the file i will create?

please explain more about the third phrase and explain exactly what should i do step by step.

thanks a lot

Let B=be a list.

How can I sort B as BB=?

Hello

I need to solve the Bending Vibration of Euler-Bernouli Beam Problem and I keep getting stuck. I start with a fairly straight forward fourth order differential eq. Using the dsolve command gives me the general solution

Y(x)=A*sin(a*x)+B*cos(a*x)+C*sinh(a*x)+D*cosh(a*x)

Maple insist on using e^(x)+e^(-x) instead on sinh and cosh - but it's the same. So far so good.

My specific problem is a clamped-pinned beam of length l - so my boundary conditions are (correct me if I'm wrong here):

In the clamped end at x=0: Y(0)=0, Y'(0)=0

In the pinned end at x=l: Y(L)=0, Y''(0)=0

Using both the dsolve(ode,ics) and a dsolve(ode) and then solve(ics) both results in the trivial solution Y(x)=0 - which is wrong - I know there is a tan(a*l)-tanh(a*l) solution.

To get a easier and well documented example to solve by hand, I also tried with a simply supported beam. Boundary conditions are then:

Y(0)=Y(l)=0

Y''(0)=Y''(l)=0

Same result - only the trivial solution Y(x)=0 and If you solve it by hand you get a sin(a*l) solution.

What am I doing wrong? Is it syntax error on my part or what?

I have attached both my maple doc and a pdf with a walkthrough of the correct solution.

Any help would be appreciated

Kind regards

Is there a way to simplify the above equation in maple?

and plot  function I? This I is the area which I wrote at the paper.

Could you give me the code which can be used to solve the ODE by numerical method and plot I with respect to t?

I think I have write down everything clearly but if you feel confused please ask me.

I am eager to know the code. Thanks very much!

Hi all

I want to analysis this beam  (a simple and a tip rotational spring) in Maple to find the first four Frequencies...

Please help me

Need help for manipulating tensor with the physics package.

I ask some questions about this.  But each time, I am refer to the help pages.  If I ask again some help, it is because I can't not start with the information on the help file.  It is written for people that already know General Relativity (GR).

So this time, I have created a document (attach to this post) where I ask specific queations on manipulations.  My goal is to ccrreate a document that I will put on the Applications Center.  I promess that those who will help me on this will be cited in the document.  This way, I hope to create an introduction on how to use tensors for beginner like me.

Then, with this help, I am sure I will be able to better understand the help page of the packages.  I am doing this as someone who is starting to learn GR and have to be able to better understand the manipulations of tensor and getting the grasp of teh meaning of all those tensor.  For exemple, the concept of parallel transport on a curve surface.

Thank you in advance for all the troubling I give you with this demand.

Regards,Parallel_Transport.mw
