# Math Help - green's theorem problem

1. ## green's theorem problem

Hello, I want to apply green's theorem to:

$\int_C 2xds$ where $C$ is the line that delimit a circle centered in $(0,0)$ with radius=1

green's theorem says:

$\int_C (f(x,y)dx + g(x,y)dy)= (...)$

So, how can I apply it?

Thank you!

Your equation is then going to be $x^2+y^2=1$ which is a circle of radius 1.

Green's Theorem:
$\int\int\frac{\partial M}{\partial y}-\frac{\partial N}{\partial x}$
