Could I set x = sin (y)? If I can, then the limit in that instance would be infinite, thus proving that the limit doesn't exist, right?

NettetWhen x = 0 or y = 0, f(x, y) is 0, so the limit of f(x, y) approaching the origin along either the x or y axis is 0. Moreover, along the line y = mx, f(x, y) = m2x3 / (x2 + m4x4). As x approaches 0 this expression approaches 0 as well. So along every line through the origin f(x, y) approaches 0. Now suppose we approach the origin along x = y2.
