If Pdx+Qdy is locally exact in R,prove that $$\int$$Pdx+Qdy=0 for every cycle Y-0 in R.

I'm a bit confused by this. You titled this "complex analysis". But refer to an integration in "R`" and appear to have a real integrand.

What, exactly, is your definition of "locally exact" and what do you mean by "R1"?
