Let f(x, y) = (2x ^2y) /(x^4 + y^2) . We will investigate limiting behaviour of this function as (x, y) approaches (0,0). (a) Show that if we approach origin along any line that passes through the origin, f approaches to 0. (b) Approach the origin along the curve y = x 2 , what does f approach to? (c) Does f have limit at the origin? (d) What is the conclusion? Comment on the result.
