Mathematics I20815 marksNumerical: limit of multivariable functionLimit and continuity

If f(x,y) = fracxyx2 + y2, does lim(x, y) to (0, 0) f(x, y) exist? Justify.

If $f(x,y) = \frac{xy}{x^2 + y^2}$, does $\lim_{(x, y) \to (0, 0)} f(x, y)$ exist? Justify. [5]

Given data: - Function: $f(x,y) = \dfrac{xy}{x^2+y^2}$ - Point of interest: $(x,y) \to (0,0)$ - Task: determine whether the limit exists. All data present. To test a two-variable limit, approach $(0,0)$ along different paths. If limits differ, the limit does not exist. Path 1: along the x-axis (
