hi

thanks for your responding, but i need the analtical solution not numerical . could u solve it again

diff(x₁(t),t)+x₁(t)+0.03x₂(t)+0.01y₁(t)+0.02499y₂(t)+.009y₃(t)=0

diff(x₂(t),t)+0.833x₁(t)+0.69985x₂(t)+0.13745x₃(t)+0.02499y₁(t)+0.06245y₂(t)+.00227159y₃(t)=0

diff(x₃(t),t)+0.109073x

Hey,

I have linearized the following system and I want to extract the linear matrices (a,b,c,d) form the solution. The program is as follows:

Hey,

I am trying to linearize a Statespace and extract the linear matrices from the solution. Using following example, can you explain how to extract the matrices a,b,c,d.

hi

would u please to help me in solving this system of this equation.

Hello,

I am wrting a program to generate the kaplan york map,

i am suppose to ouotput a sequence of x,y points

I have written my program, but am having a hard time getting the map.

In my program i return x[n],y[n].

After i read my program into  maple, what commands do i use to produce the map?

Please could you help me answer this, Thanks!
Use a nested for loop (that means two for commands, with one inside the other) to create a list of all pairs [a, b]
 where a and b are positive integers from 1 to 20 and a/b is also an integer.

hi,

 how i unsubscribe data/questions from maple prime?

It found the first four number of this sequence fine but for some reason it wont find the limit as it goes to infinity. I think it should end up being 2sqrt(3)/5 or something like that.

Hello everyone, new member here. I've been working with Maple 16/Mathematica 8/Matlab to find the determinants of some symbolic nxn matrices (a1,1 a1,2 etc). Matlab is able to do them quite easily but when they start getting too large it starts truncating them down to 25000 terms. Mathematica works like a charm but I want to beable to verify the results with Maple. Maple does great up to 7x7  but at 8x8 it seems to also truncate results like Matlab and past that...

Hey guys.

I've been using a format where everything, math and text, is in black. The awnsers come out in blue.

Some coleges use a (ugly?) format where the equations are in red and are, in my opinion, less easy to read and take longer to type down.

So my question is simply this: Can I do everything using the black format I'm used to, or are there certain things that I MUST use the red format to compute?

If there are...

Hello there,

I tried using your HTML window that can be activated from your editor to write a post. I intended to use HTML TT tags to display some MAPLE input, and everything previewed fine. However when I looked at the actual post after I submitted, the content between the TT tags had disappeared. Tried it twice. I have a feeling you are validating your HTML but some regex does not know about the TT tags and eliminates them.

Best regards,

Dear friends,

I recently saw an interesting integral at this link.

It seems to be another case where the integrator (Maple 15 (X86 64 LINUX)) somehow looses his/her bearings.

When I try the following command: int(1/(sin(theta)+cos(theta))/sqrt(sin(theta)*cos(theta)), theta=0..Pi/2); I get an answer that is fairly complicated...

Hi all,

 I want to find the co-efficient for z^k of 2-stage hyper exponential Random Variable. That is expressed as sum of two Taylor series. I have given the code in the attachment. I have tried using convert(A(z),FormalPowerSeries,z) with op([1,1],..), but it didn't work.Coefficient_Extract_.mw

Dear Maple Users!

I'm quite beginner in Maple. I will appreciate all of your help and a guidance.

I have written the simple procedure (in attached file) and it takes about 40 sec to make

one cycle on i5 2.8Ghz, 4Gb RAM, Win7x64, Maple 14 x64. I believe that it can be solved much 

more faster.

What are the ways to speed up my procedure?

Hi there,

I am calculating he rank of a matrix in Maple and I have a result. However, I want Maple to show me the intermediate steps that it used. I know that the rank function uses gaussian eliminations. Is it possible to make it display these steps? 

The matrix is 8*8 so I think it is taugh to use the tutor tool. 

I tried ShowSteps but it says that rank is not a valid problem.

Any ideas?
