Application of a Limit of a multivariable function..HELP!! 1. The problem statement, all variables and given/known data if f (x,y) = (xy^2)/(x+y^2). prove that for every real number a there is a path along which f (x,y) will approache a, as (x,y) is approaching (0,0). 2. Relevant equations f (x,y) = (xy^2)/(x+y^2) A as a element of R (x,y) approches a, as (x,y) approaches (0,0) 3. The attempt at a solution Don't know where to begin, any help would be great!
