Hello everyone,
I need some help with this one:
I need to write a routine that tests
the irreducibility of a polynomial over
the field Fp , where p is a prime.
It should return TRUE if the polynomial is
irreducible over Fp and FALSE if it's
not.
I can use the theorem below:
The polynomial x^(p^n)-x is the product of
all monic irreduble polynomials over Fp,
of degree that divides n.
So, any ideas?
Thanks in advance for your time!

Hello all, you were very helpful the last time I had a question, I hope you can help me again here.
I have a system of differential equations that can be manipulated in two way, each has its own problems
1) I can define the system of equations including a piecewise function. The test of the piecewise involves the ratio st(t)/sz(t) being relative to 1. When I attempt to dsolve,numeric this formalism it gives me an error that it cannot convert to an explicit first-order system (not that I asked it to convert by the way).
2) In place of the piecewise I can have int(1/(1+sqrt(st(t)/sz(t))*sin(theta)),theta=0..Pi) which should evaluate to a real number, and is incidentally where the piecewise function comes from. However then dsolve tells me that it cannot have an integral in a differential equation.

Hi;
I am Abdul-Kareem from Iraq. I have BSc in computer since and BSc in electrical engineering. Now I am student in computer engineering to get MSc degree in Information Technology engineering. My research is "Design and Implementation a Multicast Routing Algorithm for a Network".
Please I need more information about my research and the related topics. Thank you .
Best regards.

I'm a new mac owner and for a course i need to download and use Maple 11. So I installed it and opened it...andrun for 15 seconds but then a warning will pop up saying Maple Initialization Error and then "invalid or missing license file" followed by computer jargon i can't even understand. I've looked at Maple and Mac support sites alike to no avail. I suspect it had something to do with my firewall, in which case i'd be grateful for so direction on how to correct it. Thank you for your time.
sincerely
your friendly Maple 11 (would be) user

Hallo,
I have a problem with LSSolve that is quite strange. When I give the command
Optimization:-LSSolve( e );
I get the error "invalid optional parameter or workspace size", while if I send the same problem data to the other solvers, ie, as
Optimization:-Minimize( e^2 );
or as
Optimization:-NLPSolve( e^2 );
it seems to work, despite the fact that the same solution method is used (method = modifiednewton).
The problem does also depend on the size of the problem. If e is small and contains only 4 variables it works with all the solvers, but if it contains 6 variables or more LSSolve doesn't.

Hi all,
I'm sort of new to Maple and I got the following problem (just an example):
I have 3 equations of the following form:
sin(x)=c+d;
cos(x)=e+d;
tan(x)=e;
Now i want to solve the set of eqns to the variable c by automatically substituting d and e.
The result should be:
c=sin(x)-cos(x)+tan(x)
Furthermore it would be very good to know, how to specify which variables should be subsituted and which should remain.
I tried variations of eval, subs, algsubs and solve..
Help would be greatly appreciated!

I have been experiencing the following problem:
I define for example the expression x^2 and use the context menu to get a 2D plot then I define another such as 40-x^2 and drag it to the plot region and nothing happens. Has anybody encountered this problem before? Is this a bug with Maple or my computer?
Thanks

I was given the matrix:
A=
1 0 -2 -1
-1 1 1 0
1 1 -3 -2
0 -3 3 3
and told to reduce A to row echelon form using the AddRow function several times. I tried maple's help with no luck. Can anyone help me get started or at least clarify the AddRow function.
Thanks,
ian

Hello,
I would like to know if Maple 11 is like Scientific notebook? Is it easier than Scientific notebook? does anyone know?
Thanxs.

Hi all,
probably a simple question: I have a piecewise function that I want to invert. The actual function is the result of a couple of calculations, but here is a very simple testcase:
F1:=y=piecewise(x>=0 and x

Hello there,
how do I do a flux integral of (3xz,2y,0) over the hemisphere x^2+y^2+z^2=4 with z>=4 with Maple?
I've tried to modify the command for 'Sphere' but it didn't work and I'm not sure what the 'Surface' command does since it gives weird results...
Thanks very much!!

I want to create a Maple symbol consisting of a subliteral with a right arrow over it. If I create the subliteral with the third entry in the Layout Pallette and then use the second entry in the Accents palette to add the RightOverArrow, then I get the message "Error, invalid overscript".
Example: Subliteral from Layout Palette, type "V", tab, type "x", Highlight the entire entry and select RightOverArrow from Accents palette, type

How do I graph inequalities. A simple example would be graphing y>x-2 where the area above the line y=x-2 would be shaded. What I really want to do however is check my work for the graph of:
|x-y|+|x|+|y| where | | is the absolute symbol.

Is this thing called Interval Math? Can Maple do it?
Is this thing called Interval Math? Can Maple do it?
I am not about if this is called Interval Analysis. The thing in my mind is that I know my Monte Carlo simulation yields a result with an error tolerance of 1e-5. And I wrap that MC simulation component into a more complicated expression and form a function, I want to know the error bound of the whole function involving the MC component. Can Maple do this?
The same applies to analysis about round-off error. If I know a sub-expression has a round-off error of 1e-6, what should the error of the main expression involving this sub-expression be?

how do you remove the right palette dock only
