No that way I could have chosen infinity at 10 or lower values also. f ' will go from 0 to 0 through positive values only. But how can I claim then that my solution is infinity independent. Because if I change the value of infinity whole solution changes.


Moreover at 15.6 the value of f ' is sufficiently close to 0 but value of g (0) is about 0.15 which is far greater than 0. g (0) goes to zero at about eta=25.

So  can I get rid of the problem?  

What's wrong?
I need to minimize (z-Z) T.E-1. (z-Z).
How can you see in the first Call to LSSolve worked. By introducing objectivejacobian I have problems

Dear All,


I would like to ask either MAPLE is capable to solve >2 boundaries value problem.

Actually I'm solving a system of ODEs in a membrane divided electrochemical cell, basically a REDOX process.In 1 part I have 2 species reacting and in another part I have 3 species reacting , 2 of the species exist in both part.

At the end I wanted to coupled all the species together.

So basically I have 4 boundaries and I would like to solve it simultaneosly.



My Maple 13 puts small curly brackets to the left side of an expression and this causes several problem for me. What should I change to write good ones? (I mean normal, big brackets, not small brackets to index.) (I use the AltGr+b combination to write a left curly bracket.)


Hi, again, I am a physist. It is convenient to solve problems in presence of units. I have a equation (1-variable) including a erf function to solve. As I substute all the constants (with units) and then use 'solve'. It returns a warning without any result. I am not really familiar with the numeric package in maple. Could anyone give me some advice? Thank you.

How to change this general form to solve :

How to calculate with Maple Fourier coefficients on some numerical valued functions and how to calculate and plot the 3 partial sums :


Function B : on the interval [-phi, phi]

f(x)= NUMERICAL (x – phi/2) + NUMERICAL (x+phi/2)


Function C : on the interval [-phi, phi]

f(x) =  NUMERICAL (x+phi/2)

I enclose Maple general solution to the PDF heat equation in 1 dimention.


I need corrections of it to enable me to calculate the heat equation in certain conditions :

 du(x,t)/dt - d^2/x,t)/dx^2 = ;   t>0, x belongs to interval [0,phi[

with boundary conditions :

u(x,0) = sin(x)cos^2(x) ; x belongs to interval [0, phi)

u(0,t) = 0

u(phi,t) = 0  ;  t is still t>0

In the Belgium lottery they pick 6 numbers out of 42   (  there can't be 2 equals numbers being picked out )
Now for my maple homework , i must do some exercices in maple

1 ) Simulate the lottery
2 ) If you partici

hi all! i am **brand new** with maple 13 as well as trigonometry, which i am using the program for. i have figured out how to plot the unit circle with the command:

>plot( [cos(t), sin(t), t=0..2*Pi] );<
