I am setting up a new machine.

I was running Maple 13 on another machine running Fedora Linux 13.   I don't remember if I had any problems setting it up, but it was running fine.

But I removed it from the old machine and installed it on the new machine which is running Fedora 14 Linux.

Maple 13 loads but I get a message from SELInux about a problem with Maples's mserver and execcstack.   ...

I have problems with a variable that is given only implicitly. Maple provides incorrect answers but I am not sure where I make the mistake. Thanks for any comments! Here is what I do:

(1) I use "assume" to set properties of two paramters a and b.

> assume(a > 1);
> assume(b > 1);

(2) Since the variable "x" is given only implicitly, I define an implicit function following the description in the thread "How to define an implicit function in Maple?".

Hi, i want to overload the operators of union, intersection etc. But i do not know how to start this. kindly provide basic help. thanks.

Here is the info that i have i need to plot a piecewise-defined funtion that has a value sin(x) between -2*Pi and -1, value x-1 between -1 and 2, and a value of cos(x) for x between 2 and 5. Can anyone help me?

Hello,

After using the following command

print(plots:-display(%,%%)):

I generate a graphic. This graphic is possible to export as JPEG format using the mouse (selecting the option to "export").

Nevertheless, I would like to export (in JPEG format) this graphic (plot) using commands of Maple. How could I do that?

Thanks a lot for your attention,

Jean-Jacques

I am attempting to create an interactive number line.  I would like to allow the user plot a point on the number line with the mouse.  The value of the point plotted would be passed back to a Java program.  Can Maple do this? What is the best way to implement this?  

Thanks

Hi,

I'm a beginner in Maple and I struggle to plot the function under a number of constraints.

My function has 2 varying variables (lambda and m):

d:=(lambda, m) -> (0*lambda*m*1*0.2533*5.251234*(9)/2/((4*5.251234-1)^2)+ 1*((m*lambda*1*0.2533)/4 + (1*0.048236*(5.251234-1)*5.251234)/((4*5.251234-1)^2)))-(1*0.048236*0.2533*(0.2533-0.048236)*1*(1+m*lambda)/((4*0.2533-0.048236)^2)+ 0*lambda*m*1*0.2533*5.251234*((4*5.251234+5))/2/((4*5.251234-1)^2));

Hey there,

i have (for example) these two B/W images and would like to calculate the displacement of the cross via an image correlation.
does anyone has an idea how to succeed???
is the Correlation function in the Statistics package usable for this task?
thanks in advance!

here mentioned:

275305224 is the third 91768409 gonal number.

can you tell me in which of these algorithms we will reach to number 91768409 ?

How to solve the linear system by using maple

2y' + xy =2  with y(0)=1

Hello,

I want to solve the following equation:

equ := 4*arctan(x)-4*x/(1+x^2) = 0

so I use fsolve(equ,x) to get all solutions of equ, but only get one of the roots:zero. Actually, equ has three roots, as the picture which can be generated by the following commands illustrated.

f1 := arctan(x):

f2 := 4*x/(x^2+1):

p1 := plot(f1, legend = ["arctan(x)"], color = red):

p2 := plot(f2, legend = ["4x/(x^2+1)"], color = blue):

as you know the number of solutions for order 3 to 5 magic squares is as follow : 
(not counting rotations and reflections)

order 3: 1 solution

order 4: 880 solutions

order 5: 275305224 solutions

higher order: unknown ...

in the first look at 880 , simply appeared it can constructed by
2x5x8x11 (every factor increased by 3)

Just a question about Maple's formatting.  When I type parenthesis, brackets, or absolute value bars, how do I control what size they are displayed?  I'm typing a bunch of expressions as in-line comments for an assignment, and there are multiple parts with parenthesis within brackets, etc.  On certain lines, ever time I put a space after typing, the size of brackets on a previous line will alternate between large and small.  I can insert spaces into random...

I cannot activate Maple 11 on my new MacBook.  I get the error message: Not enough activations left on this account.   As best I can recall, I installed Maple 11 twice before: on my desktop and on my laptop; the laptop has since crashed.

Might you be able to help me? 

Thanks,

I have the equation to calculate the legendre functions , but i am trying to find a way to form a loop so it would be less time consuming to find for a series of values.

Pn = sum((-1)^i*factorial(2*n-2*i)*x^(n-2*i)/(2^n*factorial(i)*factorial(n-i)*factorial(n-2*i)), i = 0 .. (1/2)*n)

This is the general equation , as you can see there are different values of P like p0,p1,p2,p3...depending...
