Find the limit of the function $$f(x,y) = \frac{\sin(\sqrt{x^{2}+y^{2}})}{\sqrt{x^{2}+y^{2}}}$$ as $(x,y) \to (0,0)$. Assume that polynomials, exponentials, logarithmic, and trigonometric functions are continuous. [Hint: $\lim_{t\to 0}\frac{\sin t}{t}=1$.]

$\lim\limits_{(x,y)\to(0,0)} \frac{\sin(\sqrt{x^{2}+y^{2}})}{\sqrt{x^{2}+y^{2}}} =$
(Enter DNE if the limit does not exist.)
