let D be simple connected Domain and C be simple close curve in D.
then by cauchy integral theorm ∫(z) dz over C is zero.→let this be my 1st equation.
but by cauchy integral formula for a point (a) inside C, we can say
f(a)=(1/2∏i)[closed integral over c]∫f(z)dz/(z-a)
NOTE f(z) is analytic function in D.
but substituting [closed integral over c]∫f(z)dz=0 from equation 1,
we get f(a)=0, for all a belonging to C but which is not true.
now where i am wrong ?
i don't get the intuition behind cauchy integral therom and formula ,
would be glad if someone helped me.
