Thanks a lot Markiyan, and I am sorry I may have overlooked this already answered question. But, now I have just one more thing to know. On using AllSolutions = true in solve I get the answer as x = _z1~ ∏ / k, I then try to subs my fav symbol N instead of _Z1~, but Maple doesn't take it! It keeps it as it is. What kind of constant is this _Z1~, I had thought it to be the same as _C1, which is used by Maple while solving any ODE.

Reason why I want to...

I am using the function solve() to find roots of a trig. equation. Such as for sin(k*x) = 0, Maple retuns x = 0, whereas I expecting to get  x = n ∏/k, for n = 0,1,2,.... I am sorry I am new to Maple, can anyone help me get what I am looking for?

Thank you

Has anyone seen this form of a nonlinear equation with respect to X, but linear with respect to Y & Z?  I provided a contour plot within the region for all 3 variables between -2 & 2.  The plot is actually Z*conjugate(Z) so that the magnitude is above ZERO.  If I am correct I may have seen this before in orbital mechanics, but my undergrad years are a bit...

Hi,

I have enjoyed Maple computer algebra system as a platform for some work on prime constellations.  A summary of my work is here -

https://sites.google.com/site/primeconstellations/

At the bottom of the page are 3 relevant files and the filenames start with "A constellation"  Two of those files are .mw files.  The code searches the integers for solutions, and it works fine, but after about half a day, it consistantly crashes.  I...

How to plot a dynamical system as x' = f(x,y,z) , y'=g(x,y,z) . z'=h(x,y,z) ?

e.g.    x'=(x z )/y - x - 1

         y'=x y - 5 x z + y

         z'=( x z^3 )/y+( z^2)/y+6z

Hello!

I am trying to solve the differential equation:

for , 

From the page:

http://www.maplesoft.com/products/system_requirements.aspx

it would seem like ubuntu 12.04 is not officially supported for Maple 16. Could someone from Maplesoft comment if there are plans to add support with perhaps a patch? or will we have to wait until Maple 17?

I need to update for certain sofware, but would want to make sure I can run maple in an uncompromised way.

thanks

Hi

I browsed the forums but could not find a solution to my problem. Ii have a system of differential equations; however, I have the solution to one of the functions as an integral of another function in the system, but since the solutions are all numerical I don't know how to implement this. Here's the system and what I tried at first

#######################

eq1 := diff(W(r), r) = -(1-beta*(W(r)-W0))*(M(r)+4*Pi*r^3*p(r))/(beta*r*(r-2*M(r)));

balle := proc (L) local K, a, i, c, J;
J := L;
 c := nops(J);
 while J <> K do
K := J;
for i from 0 to c-1 do
if J[i+1] < J[i] then
a := J[i]; J[i] := J[i+1]; J[i+1] := a
end if
end do
end do;
return J
end proc

I got the error "Error, (in balle) invalid subscript selector " even if L is a list. I don't understand. Could you help me, pretty please? 

Hi everyone.

I need to plot a graph of y against x for the solutions for values of t form 0 to 0.003 seconds using

c=50m/s

beta=10

A=0.01m

L=0.5m

The equation is y(x,t) = A*e^(-beta(x-L-ct)^2/(L^2))

I also need to show that the above equation can be a solution for (d^2y/dt^2) = c^2 * (d^2y/dx^2) on maple.

Cheers if anyone could help me with this.

I think it was Acer who did the coding for a similar previous problem. I modified it to find the components of a set which sum to 150.

Why is it that it doesn't find all the solutions with {assume=nonnegint}. eg i have to run a additional pgm {assume=binary} to catch all solutions.

1. is there a procedure to catch all?

2. is there a way i can put the list and the desired sum in the input: eg SSP(...
