## Homework Statement

Let

**F**= ( -y/(x

^{2}+y

^{2}) , x/(x

^{2}+y

^{2}) ) Show that this vector field is irrotational on ℝ

^{2}- {0}, the real plane less the origin. Then calculate directly the line integral of

**F**around a circle of radius 1.

## Homework Equations

## The Attempt at a Solution

To show

**F**is irrotational we must show curl v = 0. Although I'm unsure what it means by finding it on ℝ

^{2}- {0} ?
