New issue 2676 by asmeurer: Derivatives should print in decreasing
lexicographic order
http://code.google.com/p/sympy/issues/detail?id=2676
In [62]: f(x).diff(x, x) + f(x).diff(x) + f(x)
Out[62]:
2
d d
f(x) + ──(f(x)) + ───(f(x))
dx 2
dx
In [63]: print f(x).diff(x, x) + f(x).diff(x) + f(x)
f(x) + Derivative(f(x), x) + Derivative(f(x), x, x)
But I think it should print in the reverse order, like I entered it.
Probably this should be somehow matched up with the polynomial orders.
