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

where 

 ...

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!

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 ?

c := y^2+2*y*x+x^2-y^2*x-y*x^2

solve(c);

{x = -y, y = y}, {x = y/(-1+y), y = y}

above polynomial find roots using solve

if do reverse to find back its polynomial c from {x = -y, y = y}, {x = y/(-1+y), y = y}

any command to do this? is it possible to do this? which book teach this?

I'm running simulations in which I produce many plots at once, the purpose being to compare differences as parameters are changed. I'd also like to use some of these plots for publication. I've had problems getting good-looking 3d plots. Here's a strange thing I noticed.

Export the graph by mouse-clicking, export to bitmap:

EDIT : IMAGE POSTED IN MY COMMENT BELOW

Export the garph by executing a plotsetup('bmp') command.

1. How many and which file format can be used to save a list of formulas?

2. how to append to above file?

i would like to let c# program to read the formula in the saved file

Hello,

I am going to solve 2D Laplace equation for function Φ(x,y) in a rectangule which has a*b dimension, yet its boundary condition, at least for me, is rather complex. Here it is:

d/dx(Φ)=0  at  x=0 , x=a

Φ=1  at  0<x<a/2 , y=0   

d/dy(Φ)=0  at a/2<x<a , y=0

what is the command to computing syzygy ideal in maple?
