Explanation / Answer

(cos(x)+y^2-x*sin(y) = 7, [x, y])

The solution Maple comes up with for that is

x = x, y = RootOf(cos(x)+_Z^2-x*sin(_Z)-7)

which is not much more than a rearrangement of form, with all of the hard work tossed in to the root finder. You cannot even tell, for example, that this has 6 roots near x=0 with two of them real-valued -- but out near x=-30 there are 3 real roots.

MuPAD does not appear to be useful at processing RootOf() such as the above.
