New issue 3309 by [email protected]: nsolve fails for Integral,
Piecewise
http://code.google.com/p/sympy/issues/detail?id=3309
nsolve(Integral(x*y,(x,0,5)),y,2)
ValueError: expected a one-dimensional and numerical function
nsolve(Piecewise((x,x<1),(x**2,True)),x,2)
ValueError: expected a one-dimensional and numerical function
The problem seems to be that nsolve uses f.atoms(Symbol) instead of
f.free_symbols for determining the number of free variables.
