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 = z_{2     ...}

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....

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:

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.

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!

Hi everybody:

I have a couple questions regarding tables in Maple 15.

a) For the most part, when you want to resize a table you grab the rightmost boundary and slide the cursor to the left or to the right as you wish. I have come across many situations in which the movement to the left is resticted. In other words, you can not make the table smaller than a certain size. I wonder if anyone knows what controls the minimum size. I don't seem to recognize the cause and effect relationship.

When can we expect Maple 15.02 to appear, to correct that major error of matrix multiplication and the plotting problem with the classic interface in particular?

     Now a new set of fundamental physical constants has been released, as of 2011 June, making the values embedded in Maple's package Scientific Constants from the preceding millennium a further step obsolescent.  I understand, however, that the values of mathematical constants pi and exp(1) are still current.

for simple case 2*2,  A = matrix([[0,-1],[1,0]]);

using A, i understand f(x,y) = f(-y,x)

where do other case f(-x,-y) and f(y,-x) come from?

any command to list all cases with input a matrix A?

if A has more dimensions, what will the cases be ?
