Hello Tutors,

Please help me out with a proof. Please see the information to be used in the proof. Thanks!!!

Problem 2 The 2: Under HI, f has an antiderivative in D. co.ra2 (ie, There is F such that F'= f on D)Ex BlubA Use information above to prove this.Information Needed e z + 2 milk disk Let D = B (zo ,r ) where r to means "excluding" H 1 means " hypothesis 1": f is differentiable on D lie. for each z ED, lim f ( w)-f (2) exists W- Z H 2: f is differentiable on E lim, f(z) ( 2-2 ) = 0
