How do you convert r^2 theta=1 into cartesian form?

y=x tan(1/(x^2+y^2)), representing a spiral from the origin that turns forever, to reach the origin..

Explanation:

As r^2>0, its reciprocal theta > 0

Using the conversion formula #r(cos theta, sin theta) = (x, y),

theta=tan^(-1)(y/x)=1/(x^2+y^2) to y = x tan (1/(x^2+y^2)).

I want variation of theta in (0, oo).

The graph is a spiral that approaches origin only in the limit,

as x, y to oo.. .
