Using polar coordinates, describe the level curves of the function defined by f ( x , y ) = 2 x y ( x 2 + y 2 ) if ( x , y ) ≠ ( 0 , 0 ) and f ( 0 , 0 ) = 0.

Let $$f(x, y)=\frac{x}{\sqrt{x^{2}+y^{2}}} \quad \text { for }(x, y) \neq(0,0)$$ Write $f$ as a function $f(r, \theta)$ in polar coordinates, and use this to find the level curves of $f .$
