i suppose all of us know the famous Cauchy,s formula(adsbygoogle = window.adsbygoogle || []).push({});

Int(c)f(z)dz/(z-a)=(2pi)if(a)

but could be applied the same to real plane,in fact let be the Integral over the closed path f(x,y)dxdy where f(x,y)=Gradient(g) then the integral in R^2

Int(C)f(x,y)dxdy/[x-a]=?

where [x-a] means sqrt[(x-a)^2+(y-b)^2] could be Cauchy,s theorem be applied in the real plane?..thanks.
