Sorry, Mario, I've read 3 or 4 times your post but still couldn't understand it. What do you want, exactly?

It matches well in the suggested form,

int(2/(1-k^2*sin(2*t*phi/Pi)^2)^(1/2)/Pi*phi,
t=0..1/2*Pi) assuming phi > 0, phi < Pi/2;

                           2 1/2
              (1 - sin(phi) )    EllipticF(sin(phi), k)
              -----------------------------------------
                              cos(phi)
 
simplify(%,symbolic);

                        EllipticF(sin(phi), k)

For several reasons, some of them outlined in my 2 cents comment, I don't currently submit bugs.

Yes, originally I noticed that in much larger example - I posted here the simplest possible example. Here is one slightly larger example,

solve(piecewise(Or(x=1,x=2,x=3,x=4),1,0)=1);

  {x = 1}, {x = 2, x <> 1}, {x = 3, x <> 1, x <> 2},

        {x = 4, x <> 1, x <> 2, x <> 3}

Personally, I don't have problems with RealRanges. They are well predictable. What I said about RealRange(5,5) being 5 and not {5} was just a thought that if I implemented it, I would do it that way, as well as the BottomProp name. That would be closer to mathematical use of them. The property of set-membership should be represented by a set, and not by a sequence of set members. Also, I wouldn't use in for including properties. Maybe, subset doesn't sound good for that, but it would be more natural.

ComplexRanges are different story. How can they be used?

The answers given by solve, in general, were designed as a sequence and not as a set, which also contradicts with usual mathematical understanding that it should be a set. Also, it would be more useful if solve returned something like BottomProp (which would be better named as EmptySet) instead of NULL (that is not printed) in cases with no solutions.

Better graphics and LaTeX is a recurring theme in many Maple forums during last 10 years. I posted many times about that, too. Supporting LaTeX in plots and input, better LaTeX output. Exporting plots in png, svg, and pdf formats. Improving current eps plot export etc. etc.

And what we see instead - MathML, Java, and 2D input. Things that neither you nor me care about.

Once I got a reply to that in the form - if they could, they would... But there seems to be more than that...

It looks as if he is working on improving a procedure for set operations with RealRanges that I posted at the end of that thread by adding sets to it. The first step is easy (as I posted above). The modification of solve is more complicated because of the feature of solve that I described in another pace.

For example,

a:=Or(RealRange(1,5),{6}):

f:=a->evalindets(a,{RealRange,set}, 
    s->if type(s,set) then map2(`=`,x,s)[] else x::s fi):
 
f(a);
                    Or(x::RealRange(1, 5), x = 6)

Well, I can post a pdf file here that will erase everything from your hard drive in a moment after you open it, and email me all your credit card numbers (well, maybe not all - only those that can be found on the hard drive :)

The problem is that I don't see why I should spend my tme on converting input from Mma to Maple. I prefer spending it on doing something potentially more fruitful - wiki, for instance.
