Thank you, it worked.

## Analytic solution...

Thanks for your comment.

But i need to solve analytic solution. Not numeric solution.

What it can not solving this equation by analytically?

Because i know maple can solve 2.order equations analytically.

@mehdi jafari May u please upload your last mw program?I coulnt manage to work it by copying and passing. Thanks also for the link.

## @mehdi jafari I have a one question...

@mehdi jafari I have a one question.U plot X(x).(in your terms x is t)  But what if i want to plot W(x,t)=X(x)*T(t)

I got X(x) results from numerical solution.

T(t) is i found from analytical ways from my another equation.

T(t)=-6.643572696*10^(-10)*cos(10733.58723*t)-0.8085449658e-4*cos(323.6693795*t)+0.8085516082e-4

T(t) is depend on t. So W(x,t) is showing the deplacement of a beam with changing time. How i can plot W(x,t)? This has to be something like that. If i can get equation of X(x) from numerical(I mean i am making out, X(x)=9*X^2 then i know T(t). I can plot this one. But with numerical result plus analytical solution , i dont know how to plot.Can u have any idea ?

@ilke When i have something including complex numbers, so i will use numeric. Thanks for your answer.

@mehdi jafari That means i can not find it from analytic ways? Thays why , u wrote numeric ?

@Carl Love This one I added lastly to try to solve the equation. Because i coulnt solve with 4 boundry conditions. I delete the last derivative. Nothing is changing not giving me any results.ı uploaded again with 4 boundry conditions.  beamsolving(thick.mw

## @Carl Love Thanks for your interest...

Thanks for your interest. I correct{} this .But when i did dsolve({bs[1..5]} union sys1); , it gaves me equation inclucing C6, I ,t.  From above, i have 6 unkowns and 7 data(knowing) , i am supposed to solve but it is not solving. I tried to add, delete boundary conditions but doesnt matter.

This is just some of it. What i got, when i did , dsolve({bs[1..5]} union sys1);

Additionally, If forgot to say , this is a 2 nonlinear diferantial equation solving...u(t) and w(t) are the equations. There are 4th derivative of w , and 3rd derivative of u(t)....

## Maple Problem with turkish windows user...

I found it .I am using a turkish version of windows 7.Mapplesoft already found the error.  http://www.maplesoft.com/support/faqs/detail.aspx?sid=34802 Thanks a lot.

## Maple is not working properly and symbol...

Hi,

I have the same problem.My system windows 7, 64 bit. I uploaded maple 15,16,17 . It is not working properly. Maple is not giving a error .I can make plus, minus, / , *. Except this things, i can not make differantial, intergral etc. When i want to make d/dx (x) , it is not giving results. I think, the issue is about symbolic work.My adviser wants me to learn this program and i couldnt figure it out how to download. Please help me. I really google a lot .
