WebSolution: Let f (z¯)=f (x −i y)=u(x,y)+iv(x,y) where u and v are real. Then fx =f ′(z¯)=ux +ivx, fy =−i f ′(z¯)=uy +ivy. Thus, f ′(z¯)=ux +ivx =i(uy +ivy), which implies ux =−vy, vx =uy. Differentiatingthese relations, one gets uxx +uyy =−vxy +vyx =0, vxx +vyy =uxy −uyx =0. Foranalyticity, f must satisfyCR relations ux =vy ...
