Webb4 juli 2016 · The epsilon-delta definition of a limit states that lim_(x->a)f(x)=L if for every epsilon > 0 there exists delta > 0 such that 0< x-a < delta implies f(x)-L < epsilon. Using this for a proof, then, we start by taking an arbitrary epsilon > 0, and then showing that such a delta exists. Proof: Let epsilon > 0 be arbitrary, and let delta = min{1/2, epsilon}. WebbCalculating the limit: x→0lim x2ln( xsinx). We want L = limx→0 x2ln( xsinx) Since the top approaches ln(1) = 0 and the bottom also approaches 0, we may use L'Hopital: L = limx→0 2x(sinxx)( x2xcosx−sinx) = limx→0 2x2sinxxcosx−sinx ...
