Do not use other one's answer!!!!!!!!!!!

Find ALL the analytic functions
f(z) = u(x, y) +iv(x,y) defined on D = {z € C | |z| < 1}
Vz= x+iy = D.
where 2u(x, y) — v(x, y) + 1 = 0
(Hint: Satisfying Cauchy Riemann Equation is a necessary but not sufficient condition
for a function to be differentiable at a point. Being analytic at a point is different from
being differentiable at a point. Being differentiable in a neighborhood containing a point
is different from being differentiable at that point.)
