New issue 2071 by pevzi23: Wrong limit result with expressions containing
sin/cos
http://code.google.com/p/sympy/issues/detail?id=2071
The issue 1224 was closed due to WontFix reason, but I get wrong result
even if x is real (the right answer is 0):
In [11]: x = Symbol('x', real=True)
In [12]: limit(x**(2/3)*sin(x**2)/(x-1), x, oo)
Out[12]: nan
Also, when I try expressions like limit(sin(x), x, oo) I get an error
instead of 'nan':
PoleError: Don't know how to calculate the limit(1/x, x, 0, dir=+), sorry.
