Greens theorem and geometric form

[nameVoid]

<y-ln(x^2+y^2),2arctan(y/x)>
region : (x-2)^2+(y-3)^2=1 counter clockwise
taking int int dQ/dx - dP/dy dA leads to -int int dA here my text is showing the next step as a solution of -pi not sure ..polar cords ext..

What is the geometric form of the interior of the curve (x-2)^2+(y-3)^2=1? What is its area?

 

[nameVoid]

not sure what you mean

Well what object or region does your

\iint dA

compute the area of? You need to know this in order to compute the integral.
