Hi all.

Assume that we have partitioned [0,a], into N equidistant subintervals and in each subinterval we have M sets of poly nomials of the following form:

where Tm(t)=tm( namely Taylor Series) and tf is a(final point)
for Example with N=4, M=3 we have:

now we want to approximate a function, asy f(t), in this interval with following form:

How can we do this with maple????

how can we find the ci's?????

Thanks a lot

assuming a equations likes this:

tan(x)+y*sin(x)=1;

tan(x)-y*sin(x)=0;

I want to solve this equations using LinearSolve function(do not use solve()). I  fisrtly change tan(x)=u,y*sin(x)=v and then solve u,v using LinearSolve. finally, I obtain x=atan(u), y=v/sin(x).

the question is how can I perform the above operates neatly? I know I can achive this by using a lot of subs().but is there any tools in maple do this neatly just like IntegrationTools[Change]?

I have just begun thinking of trying to make some mathematically defined objects using a 3d printer. I would be happy to hear from anyone who has done this using Maple to prepare input. Pointers for a novice in 3d printing would be appreciated.  I have access to a MakerBot Replicator 2. But the people who have it have only used it to scan objects and make 3d copies of them.

Hello,

 

Is it possible to use Maple 15 Student Edition with the same license information and purchase code both on Windows and Ubuntu?

I did a few Windows reinstalls (guess about 3) hence I used the same purchase code to activate the license that many times. Today I tried installing and using Maple 15 on Ubuntu 12.04.3 LTS 32-bit and to my dismay the license manager said, "Not enough activations left on this account." Furthermore, I have exhausted my download links and would like to know how many times Maple 15 can be activated and if the download links can be refreshed?

 

Thanks

the question

 

I already finished part a, my question is how do i define the function g with the variable k being any real value so that maple will find <f,g> = 0 (using the inner product defined)?

 

Hi everybody.

 

There are several weeks I'm on a school project and for it we need a Maplesim Simulation. It contains a sine voltage (source), a diode bridge (simplify), a condenser and a resistor. The problem is : when I want to simulate it, an error message appears : System is undetermined. I dopn't understand why I've this and from where's the problem...

 

If you could help me asap, it will be very very nice.

 

Have a nice day.

Hi

I'm using Maple 17 on Windows 8 (64-bit).

I have noticed that when I use the 'spacecurve' command and try to display it with the 'display' command, nothing shows up. I made sure that I used 'with(plots)' and 'with(plottools)', still nothing. However 'plot3d' works fine. I think it has something to do with the version of Java I'm using but I don't know what. Any help is welcome, thx

Specifications of my laptop:

Graphics: NVIDIA Geforce GT 740m

Processor: Intel(R) Core(TM) i7-3630QM (2.40GHz)

Ram: 6,00 GB

OS: Windows 8.1

Hi,

I have

Let

A:= sum(a[n]*phi(n)+b[n+1]*phi(n+2),n=0..N);

Please, I need to write this sum, using only phi(n), how can I use maple to get the solution.

Thank you very much for any idea.

Hi everybody,

In quantum mechanics, I want to draw the wave  of the electron in the hydrogen atom.  So in 3D, you will have a cricle and along the circle, there will be a cosine function that will meet after a full cercle (the standing wave that is possible).  The blue one and the red one at the same time.  But in 3D

The closest that I come to succes is with this commands:

But as you will see, the wave end at the same place as it started.  But instead of going in a cercle, is as a funny shape.

 

Thank you in advance for you trouble.

Hi

coeff dosn't work correctly in maple 17

Here is the code

restart;

E := m1*(diff(x1(t), t, t))+3*k*x1(t)-k*x3(t)-k*x2(t);
coeff(E, x1(t));
Error, unable

 

the coeff of diff(x1(t),t,t) and x2(t) and x3(t) can be determined and are true, but the coeff of x1(t) can not be determined??!!!!!!!!!!!!

How can I use maple and separation of variables ,solve the wave equation utt=uxx for a string of lengh 4 with u(x,0)=sin (Pi/2 x) e-x . ut(x,0)=0.u(0,t)=0 and u(4,t)=0.

Hello everybody,

While doing a document about quantum mechanics, I stumble on this strange behaviour.

>with(ScientificConstants);
>GetConstant(a[0]);
>GetValue(a[0])

Error message:

Error, (in ScientificConstants:-GetValue) `a[0]` is not a scientific constant object

But in the Assistant Scientific Constant, the value is there: 5.291772e-11m

Why is it not directly available like I did the first time?

Thank you in advance for your help.
