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;

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, \\

Hallo Guys,

This questions was asked 7 years ago and I hope now there is some knowldege how to do it ( else Maple sucks that in 7 years they havent figured out it yet ) ...

So basically How do you change the inline plot size window in the worksheet itself by command line ( For Noobs please do not show off your "Skills" by saying that you can do it b Mouse : I know that much else wont be here :P  and those who want to tell me how to do it in a jpeg/etc also Shut up ! ...

Hello,

I am trying to obtain an inverse of a symbolical 4 by 4 matrix in order to diagonalize it. I have noticed that the command 'Inverse' seems to find a matrix inverse almost instantaneously, whereas the Matrix Inverse command from the Linear Algebra package takes far longer - on the order of hours. Can anyone explain the difference between them? It seems like 'Inverse' is roughly speaking, an approximation to 'Matrix Inverse', however I have not been able to find...

I'm using Maple to come up with equations, and then I'm substituting in variable names for functions which I can then output to Matlab.

I haven't had any problems until I ran into partial derivates described by the D[] operator.  For example, if i have a function f described by f(x(t),y(t)) and I differentiate it wrt t, I get 

D[1](f)(x(t),y(t))*(x(t)_dot) + D[2](f)(x(t),y(t))*(y(t)_dot)

I want to make a substitution for D[1](f)(x(t),y(t)) and D[2...

Hi,

     I have a a matrix with one symbol and all others are numbers. I got this from doing 

   M := (1-x)*N + x*A :

 So my parameter is x, and N, A are numeric (real, symmetric) matricies. I want to plot the eigenvalues as x=0..1, but for a large matrix, say 25x25. Eigenvalues(M) only returns 17 eigenvalues, and more so, it doesnt keep them in the same order when plotting!

My issue is when Maple computes the...
