Question

Find a field G = P(x,y)i+Q(x,y)j in the xy-plane with the property that at any point (a,b) doesn't equal to (0,0), G is a unit vector tangent to the circle x^2+y^2=a^2+b^2 and pointing in the clockwise direction. How is G related to the spin field F?

Answer 1

huh? what 2nd vector one? and wait don't answer this until I attach something

Answer 2

ok
