Comment #23 on issue 2085 by nicolas.pourcelot: Limit code severely broken.
http://code.google.com/p/sympy/issues/detail?id=2085
@Vinzent: "I would rather implement L'Hôpital's rule for such cases."
From Wikipedia: http://en.wikipedia.org/wiki/L%27H%C3%B4pital%27s_rule
Suppose that either
\lim_{x\to c}{f(x)} = \lim_{x\to c}g(x) = 0
or
\lim_{x\to c}{f(x)} = \pm\lim_{x\to c}{g(x)} = \pm\infty.
And suppose that
\lim_{x\to c}{\frac{f'(x)}{g'(x)}} = L.
Then
\lim_{x\to c}{\frac{f(x)}{g(x)}}=L.
Since f(x) must have a limit, I don't see how this applies to cos(x)/x on
+oo ?
