 As Robert said, go to tools ->options->View and the third one has to be "Extended" instead of "Standard Maple".  Apply globally and restart Maple.  Then you will hve waht you want.

 but like it's said in Wikipedia, the command "find" under Windows is the same thing.  Both you have to start a terminal with "cmd"  To test this, I search for the expression "partitions" in my *.mw.  The result is a list of file with that word.  But there is in the list a file that I know there is no occurence of that word.  I open the file with Maple and indeed, it's not there.  So the conclusion is that the word is in the codes of the file.

That's because the command is searching the string and cannot make the difference between the codes and the string in the worsheet.  So it's not  command Iwill use unless someone knows an option to add to the command.  Thanks anyway Robert.

 Bloated is the right word.  But I still prefer document mode.  So I will not change that.  That's why I wonder why, after créating a Maple Reader, Maplesoft doesn't develop a desktop search engine for that purpose.

So don't get me wrong.  It's simply a wish.

 Hi,

I just can't retrace the link where I found this series that I wrote on a piece of paper.  But in Wikipedia, under "Ramanujan", I found this equality.

 

 

So I think that the series was wrong or it was missing the continued fraction part.

 Thanks Pagan.  I did  edit the "Action When Value Changes" properties of both sliders.  Works like a charm.

 In the Plot0 properties, on "action when clicked", I have

Do(%Plot0=plot(ths(%Math),x=-2..2));

and like you mentionned, I need to have a first plot. Then, doing exactly what you told me works perfectly. I know that if I want the plot to be updated as the sliders move, I need to get the properties of both sliders.  But in class, I change the value of "a" and "b" then asked what the plot should look like,  Then I click on Plot0 to confirm their guess.

Thanks pagan!

 I check the box "Make execute code the...." of Plot0

But when I right-click on Plot0, the context-menu doesn't have the choice "Manipulator".  I only have
cut, copy, copy full precision, ..., paste and the last one is "Component properties..."
???

eval(M, f = ((x,y) = x+y))

should read
eval(M, f = ((x,y) -> x+y))

 ... I could use the label of the matrix (CTRL+L)
eval((3))
and it didn't work.  But I like the second suggestion.  Thanks Joe.

X := [25, 30, 35];
Y := [25, 30, 35];
Matrix(3,3, (i,j) -> f(X[i],Y[j]) );
                                     [f(25, 25)    f(25, 30)    f(25, 35)]
                                     [                                   ]
                                     [f(30, 25)    f(30, 30)    f(30, 35)]
                                     [                                   ]
                                     [f(35, 25)    f(35, 30)    f(35, 35)]
f:=(x,y)->x²+y²
How do you do to force the evaluation of the Matrix without rewriting 
Matrix(3,3, (i,j) -> f(X[i],Y[j]) );

 In the worksheet mode, you can add a new line (that begin with the > character) by doing CTRL+K.  CTRL+J will add a new line before the line you are.  When programming a procedure, you change line by doing SHIFT+ENTER.  When you are at the last line (usually end proc:), you simply clik ENTER to tell to Maple to execute the proc.

 it should read:

>plots[display]([H, P], view = [-.5 .. 35.5, default], axes = frame);

instead of e^x, if you are in 1D input, it should be exp(x)
if you are in 2D input, remember that the letter "e" is not the same as the "e" in the palettes
(Common Symbols and Constants and Symbols).
In the first case, it's only a letter of the alphabet and consider in you case as a symbol by Maple.
The second case it's the natural base.
Taking this in account, I can plot the function without any problem

 I copy and paste i1 form Pagan and I get this:

> restart;
> e1 := rect(t-1)*exp(-I*omega*t);

                      e1 := rect(t - 1) exp(-I omega t)
> i1 := int(e1, t = -infinity .. infinity);

      i1 := int(rect(t - 1) exp(-I omega t), t = -infinity .. infinity)

Why???
