hello, i'm using maple, in order to draw a graphic in wich, different functions are plotted, 
these functions came from one with 4 variables, wich represents losses in a phenomenon (extraction) depending on diffenrent variables, so my objective is to varry only one parameter and then draw its curve, and this for each parameter ; i had 4 functions.

with(plots):

f1:=plot((n-1)/(-1+n*10^(6.77*((n-1)/n))), n=1.0537..1.2688):

f2:=plot(0.2365/(-1+1.2365*10^(0.0155*O)), O=76.42..99.92):...

Hellow,

 any one know how to solve the second order differential equation using finite element method (Using Linear shape functions)

I have written the maple code to calculate time domain value of the laplace domain equation. It contain slowly converge double series so that I used epsilon algorithm to accelerate convergence. one summation contain 7 terms and another summation terms reduce to 850 terms after the use of epsilon alorithms. I also used deHoog algorithm with 9 terms to obtain time domain data but maple give the following error:

Error: (in evalf/exp/general) object too large

Do...

If I have the parameters-(v,k,lambda) of a combinatorical design, I wonder whether I can get the incidence matrix of the design or not with maple.

Remark:v is the number points of the design; k is the number of points on each line; lambda is the number of points common on every two lines.

Thanks!

 

 

Here is my sheet. non_linear_P2_last_q.mw

In this problem I have achieved every thing what I aimed, thnaks to the wonderful people here!!!

I am looking for a way to do it in a more structured way meaning the calculation of Jacobian in the attached sheet is somewhat manuel, though I wonder does maple has some other way?

Hello,

I'm solving a system of 3 second order ODE's for 3 unknown functions, using dsolve. But in the output, I receive various sets of solutions which contain only 3 constants of integration. A friend solved the same system but in Mathematica, and received more constants of integration. 

I guess this has to do with the issue that Maple omits additive constants of integration almost everywhere. 

Is there some solution? i.e. some way of using...

I am looking for a numerical scheme which can easly handle such type of problem.

I already had the analytical results of this problem, now I want to know how to treat this problem numerically.

Any idea, then please let me know.

Thanks

Hi every one,

How can I get bouble Curl of this equation

 

 

 

In the above equation, the first term has the Laplacian, the second one has the gradient and in the term "k" is the unit vector and also u=(u1,u2,u3). sqrt(R) is a constant. 

 



Hello,

 

we have to create program which shows chemical concentration changes, but this concentration depends on time and distance along the longitudinal axis. So we have to put numbers into the left side 41x41 matrix from 3 equations:

A:=1, B:=1,E:=0.2, Δx:=0.25,Δt:=0.025.


first when i=0;

i want to write a program to simulate a walk of a drunken sailor who walks out of a bar at the centre of a city. the city has a regular pattern of 24\24 square blocks. the sailor doesnt know where he is going and how to exist teh city. the question is how many blocks will he have to walk to exit the city?

let him start at the centre of the city and assume that he exists the city when he reaches either north, east, south or western borders. it can happen that he wlks...

Hi,

I am using Maple 13 under Windows 7. I have been using Maple for quite a while now, and all of a sudden Maple has decided to start playing funny games.

Whenever I go into the Maple Portal and click on one of the hyperlinks, the Maple session locks up. The first time this had happened, I had been in the Maple Portal for half an hour.

It doesnt respond to any clicks, including trying to close the Maple window. The only way to close it at this point is to crash it via the Task Manager....

I'm writing a maplet and I would like to put in my MathMLViewer two equations. Each equation in different line. How can I do this using MathML[Export]() while setting the value of MathMLViewer ?
