Hellow,

 any one know how to solve the second order differential equation using finite element method (Using Linear shape functions)

if you have four teams a b c and d playing in a tournament and teams a and d have not played each other but all other teams have played .. typing this from my phone but its not too friendly ...  soccer scores how would you determine who would win and by what score

Hi,

I'm trying to solve a pretty complex system of equations (a 3rd order DAE with 61 equations) using the MEBDFI numeric solver but I'm always getting the following error.

error in dsolve/dae/numeric/sm_intersect. numeric exception, division by zero

I have tried to find out what the sm_interesect command is but I haven't had luck neither in Internet nor in Maple help. I have looked for similar posts...

1/x!*subs(z=0,Diff(g(z)^x, x$(x-1))) = n*x

1/x!*subs(z=0,Diff(g(z)^x, z$(x-1))) = n*x

how to solve for g(z) ?

as i do not know what do this respect to which variable from a book. so i capture this diagram.

hope that can solve it

Can you help me how to program about the interference of wave on the water surface in Maple ?

Hi, 

I've bought NAG C Library for my mac in order to use it in Maple.

However, it seems that Maple doesn't know where to search for it.
Indeed, it returns

Error, (in NAG:-h03abc) external linking: error loading external library libnagc_nag.dylib: dlopen(libnagc_nag.dylib, 129): image not found 

I've installed NAG C Library in usr/Library

Thank you very much for your help

Hi there,

I would like to introduce my self and ask you for an advice. 

I have a four linked robot that i would really like to control by the meaning of the optimal control theory. The arm has 4 actuators (giving torques U) in corrispondence of 4 rotational joints. P parameters describe the system.

I got ht edynamic system with the Lagrangian method and now I have 4 2nd order...

So currently i am trying to programm a game. for that i would need a Textbox that is updating once the player makes an input. I have a textbox TB1 and a button with the action linked. the action that the button should make is calling an external procedure which in turn updates the textbox. But i currently i keep getting the following error expresion:

Error, (in Maplets:-Tools:-Set) invalid argument(s): [TB1]::string = [7, 8, 9]

So what die i do wrong.

Dear Maple experts

I want to find the co-efficient for z^k of G(t,z)=sum_i=1^infty a_i(t) z^i where z is a function of t.

I got this error message while attempting to compute Inverse matrix of symbolic function. 

Error, (in Normalizer) unable to allocate enough memory, computation aborted

I have managed to download data for Nasdaq, NYSE and Amex in Maple. However,
my problem is how do I store the data in a txt file on my desktop in the most optimal way.
I want an mpl file so I can schedul the task manager to run the file each day in the background.
This is as far as I have come:

restart:
with(StringTools):
with(LinearAlgebra):

CSV := proc (Url) local theDLL, URLDownloadToFile, myDirectory, myFile, Destination, DL;

theDLL...

Hello

    IS THERE ANY MAPLE CODE FOR SOLVING SYSTEMS OF ODEs using IMPLICIT RUNGE KUTTA SUCH AS LOBATTOIIIA,LOBATTOIIIB and LOBATTOIIIC.THANKS

I have a polynomial system that I'd like to find ONE solution of (there may be many, so I want the program to terminate after 1 is found, since I only need to know that there IS a solution). In this system, the unknown variables are a_i, b_i, c_i, d_i, s_i, t_i, r_i, l_i, for i = 1, 2, 3, 4. Thus I want the solution in terms of these variables. The system is given below.

\begin{align*}
q & = \sum_{i = 1}^4 a_i s_i, \\
w & = \sum_{i = 1}^4 a_i t_i, \\
