$\begingroup$ @ParamanandSingh The point of the answer is to show that to 'turn-the-crank' you have to put on your 'abstract hat', and so really, for the $\varepsilon / \delta$ there are cookie cutter solutions - the interested student just has to cross over into mathematical maturity when they are ready.
