When running setup file Maple18WindowsX64Installer.exe (user has administative permissions), white blank window with no elements (buttons,menus,etc) appears and nothing happens (link to screenshot -http://s020.radikal.ru/i711/1403/d5/f33ac2f06181.png ). This problem seems due the Bitrock InstallBuilder packer which is used in last version of Maple installers for Windows. Is it possible to fix this problem? If no, could you please provide link to Maple installer prepared by previous packers?

hi all.
i have a system of ODE's including 9 set of coupled OED's . 

How do I know if I have the latest Maple build id?  What is it now?

How do i write Hassell equation: Xn+1=(Ro*Xn)/(1+Xn)^4 in maple? I need that specific syntax as a procedure with three inputs (Xo, Ro, n), so it will calculate X up to n (X1,X2, X3 and so on up to 50). I already try it and i used for loop but it doesn't work. Any ideas? Thank you.

Dear all;

I have a simple question about round and floor. Please read these line.

I have an interval [0,a].  For a given step size h=a/N; N is an integrer.

all the noeuds in this interval are X[i]:=i*h; must be in the interval [0,a].

If we make a procedure with input h, and a. ANd the oupt put x[i]. I try this

sol:=proc(h,a)

local x, N, i;

x[0]:=0;

## My question how we define the N in the next line.  N:=floor(a/N); or N:=round(a/h);

N:=round(a/h);

for i from 0 to N-1 do:

x[i+1]:=x[i]+h;

end do:

seq([[x[i]], i=0..N);

end proc;

for example

a*b v a^-1 = b

i guess Disj or Conj are Max or Min respectively

however i do not know how to max(a,b) where a and b are permutation group

reference from L group in 

http://books.google.com.hk/books/about/Lattice_Ordered_Groups.html?id=_qAFX38-pKkC&redir_esc=y

if can not calculate this, do not know how to determine whether equal in a*b v a^-1 = b

After simulate the model of MapleSim, I can only know the curve of where I need to know about. I need the specific parameter(each point value), like a piece of sheet. How I can put it of in an Excel of Word?

Hi,

I have a problem with export value from module.

Could you somene check?,

Thank's in advance.

Hi all,

By solving cubic equation in maple (version 17), I got

y1, y2, y3 formulas are computed by Maple by solving it for general formula.
But, now I got answers in real and imaginery parts, i.e

y1 = -119.0286907-1.*10^(-9)*I

y2 = .770924807+1.772050808*10^(-8)*I

y3 = 7.123944373-1.692050808*10^(-8)*I

Why, is it so?

I want answers in simple forum directly only by using these formulas. As i have to show the proof!

Thanks in advance

computer a Gröbner basis for <f_[1] = x^2*y - 2*y*z + 1, f_[2] = x*y^2-z^2+ 2*x,  f_[3] = y^2*z - x^2+ 5 > belong to Q[x,y,z], using ≺= <_grlex with x≺y≺z. compare your output to the Gröbner basis the Maple computers with a different order.

I have no idea where to start with this problem.

I know how to create arrays, but I want to assign characteristics to each position in the array; the array being a population with each member having a set of characteistics like height, weight etc. I want to be able to have some of the characteristics able to change with time, and some remain constant (those that change with time will be defined by generic equations)

I have tried looking on maplesoft for answers, and the help within maple 16, but have been unable to make any progress.

Sorry if the question is not specific enough.

Thanks in advance x

Please I need programme to solve this nonlinear couple ode with values of k_1 from 1.5 to 2.5 and eta from 0.0 to 2.0 real_work_3.mw Thanks for your help.

When I check the length of the optimal tour found by TravelingSalesman (GraphTheory package), it's different from the given result. What goes wrong?

I came to know that Chrome no longer supports MathML. Will this be an issue with Maple T.A.9/9.5? Should I require my students to switch to Firefox instread?
