Hello group,
I've asked this question in de.sci.mathematik before (2008/01/25), but
my query didn't yield any results - so here it goes again:
I'm trying to make Maple display one digit in front of the dot

Hello group,

How can I evaluate a function at more than one point?
Evoking the function with a list of values does not work.
Thx

I want to convert a lengthy (several pages) expression of trigonometry
of several angles and parameters into C++ code for numerical
calculation. I did a simplify, then edited the expression into C++. It
is not very efficient for calculation nor easy to maintain. The

Is there a nice way to extract an integrand; that is, if we have an
expression of the form Int(f,x) or Int(f,x=a..b) can we easily get f?
This issue arises when we manipulate  Int(g,z) by changing variables,
doing integration by parts, etc., to end up with Int(f,x) in which

Hello dear computer algebra patriot the Earthling,
You know from my alarm messages to the human race, yes, those
disastrous (striped!) Computers are coming!...
We have the only choice, to protect our old good carbon-based

I would like - as mentioned in the subject - to
determine the least positive value of a list.
IHow can I do it?
Furthermore, shouldn't Maple have a 'rank' function for lists?

Die Mapleists,
if I plot two a piecewise function like

                        - -- x  + -- x  - --- x + 5

Dear Mapologics,
is there a chance to fix the size of plot in the printout of a document.
I use Maple 11 in document mode. If I print the document, the e.g. graphs of
functions are very large. I can make them smaller by using the mouse, but

I have just installed Mandriva 2008 on a computer on which I was running
maple 9.5 under mandriva 2007. However on 2008 I get
X Error of failed request:  BadName (named color or font does not exist)
 Major opcode of failed request: 45(X_OpenFont)

I'm trying to use the unapply function to a vector but it looks like
it does not work this way. Here is my code
ThetaAngle := proc(n)
  local i,theta,A;

I am sure there is a better way to do this; and am a bit on the tired
side ..
so just going to ask. :)
Lets say I have boolean variables x1:x7 and the following expression:

restart: with(plots):
#Function for the tube
fR:=(alpha,t)->[(4*sqrt(17)*cos(alpha))/17+t,
(sqrt(17)*cos(alpha)*sin(2*t))/17-sin(alpha)*cos(2*t)+2*cos(2*t),

I used to coming here and asking for help about maple. Lots of
wonderful experts helped me a lot and I really liked this group.
However, now this group is no longer a maple group...
Thanks again to all of those who helped me with maple!

If the same bugs exists through numerous software releases,
I think that is valuable public information.
It just should not happen.
