In Response To 'Re: Multivariable limits'
So there's no way for Mathematica to check a multivariable limit in all directions? If you tell Wolfram Alpha to take a multivariable limit like
"take the limit of x^2/(x^2+y^2) as x->0 and y->0"
it checks to see if it is path dependent. But if you tell Mathematica a command like this:
"Limit[Limit[x^2/(x^2 + y^2), x -> 0], y -> 0]"
it will give different values depending on the direction you take the limit
