Have you tried it?  It works fine for me in 2D math.  But you might try

> map(cat, ["alpha", "beta", "gamma"], ".jpg");

                   ["alpha.jpg", "beta.jpg", "gamma.jpg"]

  eval(B, phi=Pi);
                                 2 Pi
  evalc(B);
                                  0

This is consistent with the way Maple is supposed to behave, in that results are true "generically" but may be incorrect for particular values of variables.  The problem here is only when phi is an odd multiple of Pi.

 evalc(argument(exp(I*phi));

                                phi

This one is only correct for -Pi < phi <= Pi, so I'd call this a bug.

Don't split the rtable.  Split the range of indices.

The kludge with D is necessary because of what I consider a bug in MathML[Export]: it renders D as
"<diff id='id1'/>" which is invisible.

That [animate, ..., tubeplot] is just the result of

> with(plots);

If you don't want to see it, replace the semicolon ";" by a colon ":".

The main problem is that as far as I can tell, there are no solutions to OO=0 with omega and kk in the given intervals.   It is always negative,   You are also probably running into a lot of numerical problems (roundoff error) because your numbers are very big.

My guess is that you want to plot the parametric curve [x(t), y(t)], not separate curves x and y as functions of t.  That would be

> plot([x(t), y(t), t = -6 .. 6]);

implicitplot is for a curve defined by an equation involving x and y.  For example:

> with(plots):
  implicitplot(x^2 + y^2 = 2, x = -2 .. 2, y = -2 .. 2);

Yes, that is correct.

Yes, that is correct.

Slip of the keyboard?   It looks like I saw K^p*L^(-p) on the screen but typed K^p/L^p in the Maple tag instead.
