Comment #13 on issue 2084 by smichr: limit(1+1/x, x, 0, dir='-') fails
http://code.google.com/p/sympy/issues/detail?id=2084
What about positive rationals from the left? Does this now look right?
x**(1/2) dir= - = zoo
x**(1/2) dir= + = 0
x**(2/3) dir= - = zoo
x**(2/3) dir= + = 0
Here are the other cases:
x**(-2) dir= - = oo
x**(-2) dir= + = oo
x**(-3) dir= - = -oo
x**(-3) dir= + = oo
x**(-1/2) dir= - = (oo)*I
x**(-1/2) dir= + = oo
x**(-2/3) dir= - = (oo)*I
x**(-2/3) dir= + = oo
x**2 dir= - = zoo
x**2 dir= + = 0
x**3 dir= - = zoo
x**3 dir= + = 0
repushed.
