This is what I do. 

f1(x):=sqrt(x);

f2(x):=x^(2);

with (plots):multiple(plot,[f2(x),x=0..1,y=0..1,filled=true,color=white], [f1(x),x=0..1,y=0..1,filled=true,color=blue,axes=boxed]);

My problem and question is.. it doesn't display the plot that I wanted ( a leaf) and neither does it fill it in with blue. What am I doing wrong?  

Hello my brothers and sisters..

Well, i have to say im really lost .. i have tried a lot but cant figure this out.. i cant open my math task and it only says "there was problems during the loading process" please help me guys i need this i have spent hours on this. and by the way its maple 15 on a mac.. thank you guys..

After I excute : x^2+2*x+1;   and right click on the output then I saw the CompleteSquare option in the Context Menu but after I write  assume(x>0); and then right click on the output of x^2+2*x+1; then I didn't see this option (and there are only a few options appeared in the Context Menu compared to the case before using assume()). 

Sometimes It cause some inconvenience for me since I used Context Menu on outputs from previous lines in my worksheet...

for example, how to define f(x,y)=sin(x+y) inside a triangle but f(x,y)=0 elsewhere?

hi

i want to write an integer n into all possible sums ,  i found

I'd like to hear a sound alert when Maple 15 (64bit version, on Windows 7 64bit) finishes the execution of a command.

For example, I have a very lengthy function to simplify. I use

simplify(function,size)

but it takes too long. It would be very helpful for me to hear a sound when this simplification finishes so that I can come back to see the result and go on.

Hi,

I got a worksheed with some dualaxisplots generated in a loop. As it would take some time to rightclick on each of them and export it as eps, I'm searching for a fine solution to automatically export them. For plot(); and display(); I found some nice solutions, but using dualaxisplot, I receive the following error:

Error, (in plots:-dualaxisplot) dual-axis plots are not available for the current interface or device

Hi everybody,

How can i plot a vector field and an animated curve on the same plotting window ?

Regards.

A simple question. I have this:

k*(2x+y-3z+2)+s*(5x+5y-4z+3)=0

And I want to group it by x, y, z, so that I would get:

x*(2k+5s)+y(k+5s)...=0

I'm using Maple 11.

Hey, I'm just starting to work with maple and I have no idea how i could restract a,b,c,d,e,f,g,h,i in a 3x3 matrix

Hello everyone

I want to check whether a recurrence relation produces integers. What I have written is rather messy, I ideally would like some kind of Proc where I can just put in the recurrence relation, the initial conditions and the number of terms I would like to check. Then get a result out which tells me whether the terms in the sequence are all integer. 

I have written the following (which tells me what I want to know but in a crude way)

problem := ur+dr, {con1, con4, con5}, seq(w[i] = 0 .. 1, i = 1 .. N):
problem_matrix_form := Optimization:-Convert:-AlgebraicForm:-LPToMatrix(problem):

Optimization:-LPSolve(problem, maximize = true);
Optimization:-LPSolve(problem_matrix_form[2 .. 4], maximize = true);


The above trick-conversion method works for all LP and QP problems
However it does not work on NLP problems. I have attached the workshet

Hello!

I'm studying Computational Mechanic at the Technical University in Munich. Would you please be so kind and help solving this. During my study I'm encountered with Dimensionless Analysis which I do with Buckingham Pi-Theorem. There I have to set up a matrix, each of the colums get a name wich refers to a certain physical quantity. When you are applying the Buckinham Theorem, in most case you are dealing with a rank defiecient matrix. so many of the columns of my...

I want to ask a question about parallel programming capability of Maple (for Maple15). I have a 4-core PC (intel i7 processor) running under Windows-7(64-bits). I'm making a monte carlo simulation by using maple15. The simulation is very complicated such that it includes loops and inside these loops we use Newton-raphson method (a numerical algorithm). Because of being complicated iterative calculations, one simulation needs approximately 50 hours to be completed. And this...
