Are you aware that W|A sometimes gives wrong answers for certain multivariable limits? For example, it shows the limit of the following function as 0, but the limit actually doesn't exist:
If you take x=t2 and y=kt,
The limit for t->0 is k4 / (1+k4 )3 which means the limit is dependent on k, which means that it doesn't exist. This example comes from this thread.
