i am solving a heat equations with maple but i didn't work out. if you guys can get it out plz give me code. thanx a million

diff(u1(x,t),t)=diff(diff(u1(x,t),x),x))-a*(u1(x,t)-u2(x,t))+b*(u3(x,t)-u1(x,t))
diff(u2(x,t),t)=diff(diff(u2(x,t),x),x))-c*(u2(x,t)-u3(x,t))+a*(u1(x,t)-u2(x,t))
diff(u3(x,t),t)=diff(diff(u3(x,t),x),x))-b*(u3(x,t)-u1(x,t))+c*(u2(x,t)-u3(x,t))

i need the expression of the u1(x,t)，u2(x,t)，u3(x,t) and the a,b,c are constants.

Looking forward to hearing from you!!!

I've just reformatted my computer and NEED to reinstall Maple 11 ASAP,
assignments are due soon.
I am having trouble installing it

1st time Installing)

   Everything was alrite until my cd-drive went haywire and the installiation frooze
   i then ended the task (task manager), maple as far as i know created the folder 
  program files, a few files there but NO WORKING PROGRAM is there leading to my second attempt to reinstall

2nd time installing)

"Maple 11 already installed"
  confused i decided to explore maple 11 folder, attempt an uninstall

Hello,

I just received and installed Maple 11.  (Maplesoft wouldn't sell me the student version, but I learned they have an unadvertised Home User version which is reasonable.  You have to call on the phone to order it.)  So far it's working well, but I can't figure out how to get an exact (symbolic) solution to a quartic with integer coefficients.

I'm asking Maple for simple things only, yet still (5 years later) I get nothing.

I'm creating 3 contour plots for potential functions in 3 bordering regions of 3-space,

because a continuous potential function isn't possible to define. 

After an entire worksheet worth of variable definitions and series expansions, i say simply:

CPA:=contourplot3d(VI(a,b,c,d,e)......)

CPB:=contourplot3d(VII(a,b,c,d,e)......)

CPC:=contourplot3d(VIII(a,b,c,d,e).......)

I posed an integration problem and Maple solved it so easily I decided I would like to get Maple.  I'm waiting to hear whether Maplesoft will sell me the student version.  While I'm waiting, I would like to ask this group a question I've always had about systems like Maple.  I will start by posing a problem:

Let C be a unit circle and let P be a point on C.  Draw a bigger circle B with P as center which crosses C at two diametrically opposed points of C.  What is the area of the crescent-shaped region inside C and outside B?

Hello Everyone:

I used to receive emails each time when a comment/reply was made to my questions on mapleprimes. Very convenient. Now this service either stopped to exist or something else, as I receive nothing. Can it be resumed somehow? Thanks.

I am thinking about buying Maple, but I would like to know how it does with the following problem:

f(x):=log(2-cos(x)+sqrt(3+cos(x)*(cos(x)-4))) ;
r(n,p):=(1/%pi)*integrate((1-exp(-abs(n)*f(x))*cos(p*x))/sinh(f(x)),x,0,%pi) ;
r(1,3) ;

These are Maxima commands--let me know if it is not clear what they are doing.  I am wondering if someone with Maple could translate these commands into Maple-ese and try them. (Maxima just gives up on this integral.)

The following give very different answers.

> evalf( int( ln(2+2*cos(t)^2+cos(t)^4), t = 0 .. Pi));

   -8.710344354+19.73920881*I;

> evalf( Int( ln(2+2*cos(t)^2+cos(t)^4), t = 0 .. Pi));

Hello to All,

I am just in testing process of new version Mechanics of Materials 2.0 ToolBox.

Some of Maple pictures are so good that I decided to put here one from them.

What a great Maple...

Sorry for my some immodesty...

Hello All,

     In Document Mode, I entered the following 2 lines and observed 2 different behaviors from Maple 10,

       sin(4.5)=-.9775301177         I can NOT enter anything after ..177, the output.  Here = is ctrl+=.

I have come across an integral that behaves badly/oddly for specific forms of the limits.

The integral is

Hello,

  New to Maplesoft so on a bit of an exploration here.  I see lots of applications, samples, worksheets, demos, etc., but is anyone aware of Maple packages/efforts that are full/thorough complements to any of the popular HS math textbooks in use (any/all grade levels)?  By full complement I mean Maple exercises/explorations/demos that, on a chapter by chapter basis, augment the specific topics/exercises of an entire text book.  I know any teacher can work up a sheet at anytime; I'm looking for prepackaged, ready to load and go for text books.

Hello maple users/support!

How can I access local variables of a module without having to write set_X() get_X() functions for all variables I want to read/write to?

thx for your help,
