consider the limit(adsbygoogle = window.adsbygoogle || []).push({});

when lim x,y goes to 0,0 (x*(|y|^k))/(x^2+y^4)

a-) find all values of k where the limit does not exist

b-)find all value of k where the liğmit exist..

I tried to write epsilon-delta method but I could not go further...

Which method should I use in order to show the limit is exist/does not exist?
