1. The problem statement, all variables and given/known data (Sorry, having problems with math symbols) lim f(x,y) [(x^4)y]/(x^8+y^4) (x,y)→(0,0) 2. Relevant equations Compare limits when a.) y=x b.) y=x^4 3. The attempt at a solution The solutions are a.) limit approaches 0 b.) limit approaches 1 I think I understand in order for a limit to exist, it must approach the same value regardless of which direction we approach it from. So I think that the limit DNE here because there are two different values approached. However, not really sure how to substitute values into the equation without getting zero for both a and b.
