In a Button, this command enables us to display in a Mathcontainer a   (Delta). 

D(%Mathcontainer0 = 'Delta');

However, I want to display  y. (Delta y). If I write

D(%Mathcontainer0 = 'Delta y');

Hi everybody,

I am using Maple 14 in document mode. Recently I encountered the problem with exporting polish special characters (like ąęćłóńśźż) into PDF file. Maple 14 just omits them. Why?

A new edition of The Mathematics Survival Kit – Maple Edition is now available.  It contains 25 new topics, which were created in response to requests from readers of the first edition of the book. New materials range from basic operations such as factoring and fractions, to graph sketching, vectors, and integration.

The Math Survival Kit gives students the opportunity to review exactly the concept or technique they are stuck on, learn what they need to know,...

I use Maple in high school. My students deliver their homework created in Maple. Often this involves solving a number of exercises, say 7. Not all students are completely aware of how the Maple Engine works, so I tell them to put in restarts from time to time, at least when a new exercise begins. This prevents misunderstandings and loss of time which might else happen when calculations in one exercise interferes with calculations in the next exercise. One simple example...

This guy Giorges is using Python and wget inorder to do parrallel downloading
and he is arguing that it is very fast.

Now my questions become

1) Does there exist a simple way that I can use wget without installing it ?
I dont want to bother users of my Maple application with installing a 3:rd party software.
A simple file in a specific location would be ok though

How can I display 2 followed by 1 single animation?

ie

a:=animate(...)
b:=animate(...)
c:=animate(...)

I can animate all 3 in sequence with display((a,b,c),insequence=true)  or I can animate them all at once.  But how can I animate two at once followed by the 3rd animation?

I tried

h:=display(a,b)
g:=display(c)

gg:=dispaly((h,g),insequence=true)    Which I thought might have worked however that produces multiple frames.

Whilst I am glad that Maple have finally fixed their pdf and eps plot output with version 13 (corrupted on the Mac since version 10), I would like to re-ask the question asked by peterschmid 4 in 2006: how can I control the output size of the plot?  The plotsetup options axiswidth, axisheight, width, height, appear to have no effect.

Please note that I use Maple for academic publishing, and I wish to automatically generate graphs and export them as eps files....

As a user of Maple 13, namely in computations on General Relativity & Tensor Calculus, I would like to let you know I just got, using Maple 13, the WRONG SIGN (positive Riemann scalar curvature in stead of correct NEGATIVE Riemann scalar curvature) in studying a threefold used as a 'Public Space' by Milne many years ago.

The square of the distance on the said threefold is dE^2=dR^2+(c*t0)^2*sinh(R/(c*t0))^2*(dtheta^2+sin(theta)^2*dphi^2) and you might be interested...

Can the seq here be made into an equivalent for command?

x:=[6,2,8,4]
y:=[7,5,1,3]
stepsize:=0.5
step:=seq(min(x)..max(x),stepsize)

b:=[seq([new,min(y)],new=step)]
pointplot(b,symbol=circle,color=blue)

This is code I've converted from Matlab.  Now I'm attempting to convert the seq here into a similar but simple for loop without using seq.  There is a similar code line in Matlab using a for loop but I have no experience with...

I am gettinga string from a textfield

In my program that String represent a set of 8 bits

ie. g(t)= 10101110

But I need to separate them like

n0=1

n1=0

n2=1

...

n7=0

where each n is an integer

how do I do it?

If I assign a list to a variable named depth it causes invalid object errors in for loops for Maple12

depth:=[1,2,3,4,5,6,7,8]:

for i from 1 to 4 do
  i;
end do;

Error, invalid object: mspace(height = "0.0ex",width = "0.0em",[1, 2, 3, 4, 5, 6, 7, 8] = "0.0ex",linebreak = "newline") and  1 additional error.

UncertaityofCalibrat.mw

within the attached document, is the idea that I would like to develop with the optimization package.

I want to calculate iterates for the Logistic map using the maple's symbolic computation. e.g., 

x1=a*x*(1-x):

a1=a+w:

x=x1:

a=a1:

In order to keep track of the error that builds up in each step.  But the main trouble is that it takes very long time to calculate the same even for 100 iterates. What could be the possible method to make my program efficient ? 

Please do not answer in terms of using high precision technique as I am more interested in doing it symbolically.

I have the following list, vector or set, I put it in a matrix

Hello,

Does any body know why the following code

A:=Matrix(3, 3, [[-1/23*(14+21*62^(1/2))^(1/3)-31/29/(14+21*62^(1/2))^(1/3)-13/107,0,0],[0,1/22*(14+21*62^(1/2))^(1/3)+15/29/(14+21*62^(1/2))^(1/3)-13/10-1/2*I*3^(1/2)*(-1/11*(14+21*62^(1/2))^(1/3)+31/29/(14+21*62^(1/2))^(1/3)),0],[0,0,1/22*(14+21*62^(1/2))^(1/3)+15/29/(14+21*62^(1/2))^(1/3)-13/10+1/2*I*3^(1/2)*(-1/11*(14+21*62^(1/2))^(1/3)+31/29/(14+21*62^(1/2))^(1/3))]]) ;
