Hello every one, 

Here I will recall the PDE and its numerical solutiion provided by Maple help. 

PDE := diff(u(x,t),t)=-diff(u(x,t),x);

IBC := {u(x,0)=sin(2*Pi*x),u(0,t)=-sin(2*Pi*t)};

pds := pdsolve(PDE,IBC,numeric,time=t,range=0..1);

p1:=pds:-plot(t=0,numpoints=50):
p2:=pds:-plot(t=1/8,numpoints=50,color=blue):
p3:=pds:-plot(t=1/4,numpoints=50,color=green):
plots[display]({p1,p2,p3});

I want to export data...

Hi,

I posted a problem the other day to do with this specific problem and the issues got sorted out:)

The aim of the program is to find the catenary by iteration...

It's majorly diverging though and i'm not sure why.

Any ideas?

Thanks,

Rach

Sometimes maple tends to press enter two times when I want to access a label with Ctrl+L

Here is what I mean:

This happened because it "pressed" enter 2 times. This doesn't happen all the time. Did anybody have this problem? Any way to fix it?

P.S. My space bar is alright 100%

Hi everyone

It's been a while since I last used Maple, so maybe these are simple questions

The first is:

I have a DE

eqbz:=diff(y(x),x)=-l/x^2*(y(x)^2-yeq(x)^2)

yeq(x) is a simple function of x and I want to solve it with "l" as a parameter and ic:=y(0.01)=1

sol:=dsolve({eqbz,ic},numeric,output=listprocedure,range=0.01..10^3,parameters=[l])

then I proceed to plot

ysol:=eval(y(x),sol)

ysol(parameters=[l=x]):

I have two lists viz.

m:=[0,1,2,3,4,5]; n:=[0,1,2,3,4,5,6,7,8,9];

I have to define a mapping (i.e. a Maple table) say `p` such that

(1) p(0)=0,

(2) p(max(m))=p(max(n)) and

(3) For all other i in m p(i) is a random choice from n but with condition that p(i)>=p(i-1).

Help is desperately needed. regards

Hello,

I use the module DynamicSystem to transform a state system in transfer functions. Next, i can plot Bode diagram with this module.

However, i have a little problem. I don't manage to extract only one transfer function from a dynamic system when i have several transfer functions (see example below)

I'd like to plot the first transfer function alone in fact. How can i extract y1(s) ?

Hi,

I tried to export my maple document to latex using file->export function, but it won't export file correctly. For example

in maple
> a := 5431; b := 15971; c := 20551;
> f := -a-b-c;
                             -41953

in latex

\documentclass{article}
\usepackage{maplestd2e}
\def\emptyline{\vspace{12pt}}

I have an intermittent font issue in Maple 15 on Mac OS X 10.4 and 10.5.

Every-so-often it happens that certain characters do not show in the Maple output. These are usually greek characters or somewhat more exotic mathematical symbols. I do shuffle file back & forth between my systems which are Maple 15 and OS X 10.4.11 and 10.5.8. Java id 1.5 on both of these. Occasionally, a file may also get to a machine running Maple 17 on 10.6.8 with Java 1.6, but that is...

Hi

I want to write the following summation but Maple give the following error

summation: 

I have been running Maple 11 since 2007.  Recently my PC was upgraded to Windows 7: upon reinstallation I appear to still have full mathematical functionality but can no longer save files. The "Open" button/menu are both equally unresponsive, although I can open old files by double clicking on them,

Please could you advise how I can resolve this issue.  Thank you.

Here is a link to a maple file I found describing what happens to a glider where k=.9--->  k=.9.mw

I would like to see what happens to the same glider when k=0.----> k=0.mw

***k is the strength of a propeller.

How do I determine whether or not it is a sink/source/spiral/etc based on the eigenvalues?
I was trying to use

f describe the horizontal motion

g describe the vertical motion

h := sin(t);    

g := piecewise(t < 0, Diff(x(h),h$2)+2*Diff(x(h),h)+10*x(h), t > 0,Diff(x(h),h$2)-2*Diff(x(h),h)+10*x(h));

dsolve([g,h]);

can not solve

Error, (in unknown) invalid input: diff received sin(t), which is not valid for its 2nd argument

 

f := sin(m(t));   
g := piecewise(t < 0, Diff(x(m(t...

hello,

I need to find a sollution for equation in maple 14

a*s = b mod c, where a, b, c are know integers, for example

Hello everyone;

I have a usecase in which I need to solve system of 8 equations, using high number of unknowns (16, to be precise). Currently it goes like this: Maple computes as usual for about three minutes, then it starts consuming RAM at 100mb/sec rate until my PC hangs completely.

I was wondering, if it somehow possible to solve equations with such high number of unknowns? Maybe there is some function or setting that will allow computations with less RAM requirements ...
