Hello, I'm having trouble running my worksheet on my computer, don't know why but the Solve commands just never give me output, even with easy equations.

If someone could please run this worksheet FormulasToSolve_2.mw   for me I would be greatly thankfull, I'm stuck in my research because of this...

1. can it have simple solution for convert(taylor(Qx*exp(z), z=0,5), ratpoly); as my solution have     hypergeom([-1/2i, ....?

    for example where Qx = x/m, if m is also increasing from 0 to 5 by one in each term

    How to write these command?

    is it sum(Qx*z^m/m!, m=0..infinity); but convert this result to ratpoly result in error, if exp, it will have summation,

 

hi all,

To create an observability grammian I have to integrate a matrix with some equations that are difficult to integrate due to multiple time dependent variables. The simplest expression in the matrix is:

z1^2 * sin( z5 * t)^2          (1)

where z1 and z5 are from a state space model with 5 states and are given by:

z1dot = z2     ...

This is somewhat related to the interactive stock quote importer. 

The TSX, DOW jones industrial average, FTSE 100, Heing Seng indexes are all a collection of stocks and their index reflects the movement of those stocks. 

The Dow Jones Industrial average is designated ^DJI in finance.yahoo.com but that symbol is not available in the download.finance.yahoo.com from the interactive stock quoted importer.  Is there perhaps a way I missed...

I am trying to use Tables to better organize the layout of my Document mode worksheets. I have noticed two problems thus far.1) When I use the triple exclamation point icon to execute the worksheet, sometimes the code in the Table is skipped. and 2) I put a simple plot command in one cell. The plot showed up in the cell, but the grapgh also showed up twice below the Table. If I only execute the code in the cell, this does not happen. There is no hidden code. If I...

hey,

i have a problem to get to the orthogonal point, but still there is a intersection and so should be as well a orthogonal point....

Hi,

I reach to these balance equations Equations.pdf  in my queuing system where all parameters (N, S, m, λ, μ, x) are positive integer.

I was wondering whether I can solve these (N + S) equations by Maple to find the variables (πx , -N ≤ x ≤ S ) based on the parameters?

These (N + S) variables indicate the steady-state probabilities in the system.

On the main page for the Rubi rule-based integrator, there is a table comparing results of Rubi against Maple and Mathematica.

On the face of it, the Maple results don't look so good. Maple is claimed as scoring about 82% correct on the author's example test suite. But only 42% of the suite gets an "optimal" result from Maple. The other 40% that Maple is claimed to get correct have results that are described as "Messy:

I am trying to solve a differential equations with the periodic coefficients, which have the following form:

Is it possible to a plot,  shown in worksheet, insert vertical lines using the Builder plot ?

GRACIAS

 

 

Does anyone happen to have a worksheet that implements LinearAlgebra[Generic][SmithForm] 

for Euclidean domains like Z[w], w^3 = 1, or Z[sqrt(d)] where d = −11, −7, −3, −2, −1, 2, 3, 5, 6, 7, 11, 13, 17, 19, 21, 29, 33, 37, 41, 57, 73?


If so I would greatly appreciate receiving a copy of it.

Good Morning.

I would like to know where Maple is statistics compared with other software. As a justification for the thesis i am doing. I found a page http://www.scientificweb.com/ncrunch/, but a report in 2008. I wish something more recent.

Thanks

 

 

(i^2+i*alpha+i*beta+i)*Q(n)+((-x*alpha-x*beta-2*x+beta-alpha)*n-x*alpha-x*beta-2*x+beta-alpha)*Q(n+1)+((1-x^2)*n^2+(-3*x^2+3)*n-2*x^2+2)*Q(n+2) = 0

After using diffeqtorec, there is n in coefficient, if multiply x^n/n! to all terms, i can not convert some to exponential function due to n^2, n and the difference of outer coefficient n not greater than n+2 in Q(n+2)

as i do not know the initial condition of above formula, differential equation is no use.

Hello

 

I Just shifted to Maple from TI-Interactive and i'd like to know if i can make equations and formulars without output and still using maples attributes such as when i divide stuff and it automaticly puts one under the other.

I TI-interactive i used the inser --> object and then chose the Microsoft Equation 3.0 for making equations where i write the output.

I try to use MathMLViewer with OpenMaple. Similar works with plotting:

If I issue

interface(plotdevice=maplet);

Plots are shown nicely in a new java window.

But executing

Maplets[Elements][MathMLViewer](MathML[Export](x^2));

results in the following error


Error, (in XMLTools:-ToString) could not initialize the Java Virtual Machine

What can I do to make it work?

Thanks a lot!
