Hi,
 

I had to adjust the height of the cell to make it right.  Of course (and I don't know why),  the image of the square look bigger than the lines but in the print preview, it's ok and in the pdf format too.  Here is what I have done and the result.

Sorry, can't do more

Yes, the pulley and the rope are massless.  Everything is fine now.

mario.lemelin@cgocable.ca

I have tried it in Maple 11 and 12 and it print correctly.  In the print preview, it look fine too.

I just want to be sure that I will be compatible with the others who still does not have it yet.  It's just that sometimes, I have lost informations with worksheet done in Maple 12 when I open it with Maple 11.  THis is because there is new facilities in 12 that are not in 11.  But for now on, I will do my files in 12 wich is a great improvment.  And I am still behind what I said in the brochure.  Is it ok now?

definition of the piecewise function.  It give:

About inverting the function, sorry I don't know how to do it.

Sometimes, it's better to use f_x when you talk about partial derivative.  You can do it like this:

alias(f[u]=diff(f(x+y),x))

Why RootFinding does not work?

Here is where the I1 come from:

I1 := int(cos(m*x)*sin(n*x), x = 0 .. Pi) assuming m::integer,n::integer;
                                            (m + n)  
                               -2 n + 2 (-1)        n
                       I1 := - ----------------------
                                      /  2    2\     
                                    2 \-m  + n /     

You export the data to a file like this:

with(plots):
   P := implicitplot(x*y-1,x=-2..2,y=-2..2):
   Q:= < op(indets(P,Array));

then right-click o n the output and choose:

Export As -> Tab Deliminated

save it then insert a spreadsheet.  Right-click on the spreadsheet and choose:

Import As -> Tab Deliminated

Your data will then be in the spreadsheet and as a bonus, you will be able to manipulate the data.

I found a link to a maplenet application that is suppose to give the result of a integral that you want.

maplenet.maplesoft.com/maplenet/worksheet/Integrals/Integrals.mw;jsessionid=9C5C4CC42E06FD1EFB047906DA448765.mn001

But it is very disturbing to see that it cannot do the integration of

int(exp(-q^2*x^2),x)

while Mathematica can.  Maple should develop a site in wich a student can make derivative, integration and plotting of functions.  Maybe someone know such a link?

If that response is to  me, sorry but it's the firts time I see plot use that way.  If I forgot it earlier well, I am humain.........
