I'm using Maple 11, and I have a question on switching between the input modes.
In the user manual it only states that one should go the 'tools' drop down menu, select the 'options' choice, and apply the 'maple input' mode to the current worksheet or globally.
However, after doing this I still find myself having to click on the "text" button directly above the worksheet area to have the input text stay permanently in the red colored maple input.
Is this how others also choose to permanently use the maple input in worksheets ?
Is this actually the only, or correct way ?
v/r,

If I try to solve t = 5.*x*sqrt(1.+4.*x^2)+2.500000000*arcsinh(2.*x) for x in terms of t, using solve(t = 5.*x*sqrt(1.+4.*x^2)+2.500000000*arcsinh(2.*x),x); I get a RootOf answer form. That is not very useful, so I then use allvalues(%) but it just returns the same RootOf answer. Does returning the the same RootOf answer mean that allvalues can not convert the RootOf solution into an answer that contains the roots? If so, why does solve give the root of solution when it cannot be solved? If not, what does Maple return when it cannot perform a command? I find it disturbing if Maple returns a RootOf solution if it can not solve for the roots, (if that is what is happening). It's like if I ask you what the square root of two is and your reply is that it is the square root of two. That would not be the answer to the question asked. Perhaps there is an effective way to convert the RootOf answer into one containing the roots as opposed to using allvalues(%) which doesn't do the job? Thanks for the help.

Given an expression is there a easy way to convert occurrencies of
diff, int, limit, product, sum to their intert forms? For diff one
can use convert(%,D), but for int and sum it is not the right way.
Are there other ways instead of using "subs(sum=Sum,%)" etc ?

I observe that within graphics numbers are displayed according to local
settings (so 0,001 stands for 1/1000) - no problem for me, but annoying,
actual output displays with a point as decimal separator.
For pretty display I sometimes use something as 'eval(expr, x=1)': '%'=%
which works fine in mws, but in mw it displays the eval statement - is
there a workaround for both kinds of sheets?
And saving a mws as mw does not respect the font size for 2D output (it
changes mine from 10 to 12 (and behaves odd, it always uses italics, but
we had that already i think).

Hi,

I'm trying to animate a group of spheres moving randomly in a box but am having difficulty getting the axes to show up. Specifically i want to be able to export as a GIF, for use in a presentation but when I insert a static set of axes with an arbitrary empty bit of a plot it won't let me export. I can define a set of axes as below, but i can't seem to control the size. Any ideas how to define the axes size in the following bit of maple for one sphere?

Thanks greatly in advance.

When I have defined a function and a matrix
f(x)
A[2000,1]
The matrix consists only of numbers; no variables.
Is is possible to use the function on the matrix and thus get a new matrix where all the entries are the transformed values?

I've noticed that if I'm not connected to the internet and load a worksheet in Maple-11 document mode, it more often than not loads with question marks on some of the lines. It never happens when I'm connected to the internet.
Is there some kind of connectivity between Maple-11 and the internet?
If anyone else can try this, please do and let me know what happens.
I discovered it when I was working on my cable modem and wasn't connected for a while and was loading various worksheets in maple and began seeing the question marks. Then when I plugged the cable back in they stopped showing up.

Thanks to J. Tarr, Georgios Kokovidis and others I got my dataset imported into Maple as a matrix. After having done some computations on it, I would like to export it again to an Excel file. Is this possible?

I would like to calculate
int( (1/4)*x^3*BesselY(0,x)*BesselK(0,x),x=0..infinity);
In an article authors say it is 1/(2*pi).
Could help me anybody?

I'm taking a Maple course and I cannot figure out how to convert from a number to binary (without using the convert(#,binary)). So far I have
toBinary:= proc(x::posint)
local n, k;
n:=x;
k:=0;
while n > 0 do
k:=
and I'm not sure where to go from here. I know that I need to find the remainders and decrease my n and then put it into a list and then concatinate in the reverse order.
Can someone help me out?
Thanks

Can Maple import a bitmap and then use it in a plot?
If it can, can the orientation of the bitmap be changed in the plot?
It would be much quicker and would look nicer than using the internal drawing facilities.

Dear Comrades,
I'm trying to solve a system of coupled integral equations. Does anybody know how to use IntSolve? And what's the shared library? Do I have to download IntSolve from somewhere? And is this the best way to spolve integral equations if I did?

Andrew

Hello,
I know it is possible to catch errors using traperror and lasterror...
But is it possible to also catch warnings in any way? It seems they are only messages that are printed on the screen. So, using OpenMaple/C, they can be extracted from the textCallBack stream (using id 5)... but is this also possible in the Maple environment itself, and if so, how?

Franky.

New info on the "label=" question. I open a new work sheet and enter solve({x^2-y^2=y,2*x*y*=x}). The answer returned includes RootOf(_Z^2-3, label=_L2). Then I copy and paste that solve command after the next prompt and solve the same exact problem again. This time I get the same exact answers EXCEPT that the label is now _L5 and if I solve the same exact problem a third time I get a third label. I can only conclude that the label has nothing to do with the solutions to the problem. This makes me wonder what then is the purpose of a label? Why is it returned? What significance should one attach to it? I don't want to get bogged down about what the spec says or whether this is a bug.

I would like to import a big dataset in Maple and this is giving me some difficulties.
Although Maple does have an Importdata-command, I can't figure out exactly how it works. The dataset I want to import is an excel file consisting of 2000 observations with 7 variables. Can this be done and made usefull in Maple, or do I really have to sit down and learn SAS..?
