Unformatted text preview: general idea is that if you can Fnd two paths heading for ( a, b ) such that the limit of f ( x, y ) at ( a, b ) along the paths give two dierent results, then you can conclude lim ( x,y ) ( a,b ) f ( x, y ) does not exist. So, for this problem, you need to come up with two paths heading towards (0 , 0) along which x ( y + 1) y has two dierent limits. 1...
