For a given galois field, suppose there is such a polynomial function mapping from GF(q) to GF(q): x^(q+m)+x^(q+m-1)+x^(q+m-2)+...+x^(1). I can use x^q-x=0 to "reduce" it to such the following form: x^(q-1)+x^(q-2)+x^(q-3)+...+x^(1)

now, the problem is whether this is the only method (x^q-x=0) to reduce a polynomial function mapping from GF(q) to GF(q)?

Thanks a lot.

Hi, what are possible ways to exchange data between Maple and solidworks ? Assume i have a Matrix -created in Maple- that contains 3d data for a CAD model. Is it possible to pass this data to solidworks ?

Thanks

# I want to maximize the following function: ((2*c+a-d-2*b)*delta-(1/2)*c+(1/2)*d-b+a)^2/(9*b-9*a): # under this constraints: b-a >= c-d: c-d-b+a <= (2*b-a-2*c+d)*delta: (2*b-a-2*c+d)*delta <= 2*b-2*a-2*c+2*d: a = x[min] .. b: c = d .. y[max]: # and I have the following values: x[max] := 10: x[min] := 0: y[max] := 10: y[min] := 0: delta := 1: b:=2: d:=5: # I have tried to find the maximum with NLPSolve and the option 'maximize':

I have 5 matrices, Hmatrix[1], and so on.

I can test

map(IsDefinite,Hmatrix) Maple gives the 5 answers.

How can I test using map the negative_semidefinite property?

Thanks.

Hi how to calculate improper integrals with the tutors and (if possible) showing the procedure step by step? Let’s take my homework as an example. Calculate: > int(1/((1+x^2)*(1+4*x^2)), x = 0 .. infinity);

Hi, is there a detailed list of differences between those 3 product lines of Maple ? Maybe additional packages for the pro version ? Are worksheets, created with one version, completely compatible to other ?

Hi,

I am kind of new with using maple, and I am hoping that someone can give me some help on nonlinear curve fitting. I checked out the help topics, and I thought that I had put everything in correctly, as per the help file. However when I try to do a fit to data, nothing is returned. Here is what I have input:

So, I have r^3=1/64. I need help finding r

Hi all, I'm not good at maple, so need a help from experts. I'm using Maple v.12. -part of the code- ... de2:= # Nonlinear DE is here # ics:= X(0) = 1, (D(X))(0) = 1; sol:= dsolve({de2, ics}, numeric, method = rkf45); (or sol := dsolve({de2, ics}, x(t), numeric, stiff = true, range = 0 .. 200);) Error, (in f) unable to store '1.0000000024691*{1.}^2+2000010000.' when datatype=float[8] -end of the code- As you see above, It's a simple process to solve DE. so most of the DE, like (1) below, is solved very well through the code. But my case is (2). I could see error msg as you see above.

Good day, I cannot run this maple, why?

I need help!

I'm trying to plot a sphere, and then shade-in the bottom one-third of it. Is that possible?

Also, I then need to plot a sphere with 8 approximating disks.

Does anyone have any ideas of how to do these?

have a look at this plot, i'm using standard worksheet (in classic this problem doesn't exist).

plot(sin(x),x=-5..5,tickmarks=[default,20]);

Instead of -for example- 0,5 i want decimal points 0.5

Playing with the tickmarks option would do the trick, but a "global switch" would be better.

What to do ?

Thomas
