comment How to derive this identity: $\lim _{x\to \infty} (1 + f(x))^{\frac{1}{g(x)}} = \mathrm e^{\lim_{x \to \infty} \frac{f(x)}{g(x)}}$
If $f(x)=1$ and $g(x)=1$ then the LHS goes to $2$ and the RHS goes to $e$... I don't think this is true in general.

comment Necessity of Differential Forms
Not entirely an answer to your question (it doesn't answer the importance in analysis) but for a more intuitive explanation, Tao gives an introduction to differential forms here: math.ucla.edu/~tao/preprints/forms.pdf and argues the algebraic laws of the differential forms derive from a roughly speaking more intuitive, what I would describe as: "infinitesimal geometry".

comment f(x) is a function such that $\lim_{x\to0} f(x)/x=1$
You really shouldn't assume $f(x)$ is $\sin(x)$ because you have not shown that $a$ and $b$ are unique and irrespective of $f(x)$.

revised How to prove $|x-y|\le \delta\lor |x^2-y^2|\gt \epsilon$ with the following condition?
Uses more standard epsilon and delta as opposed to e and d.

comment Terry Tao, Russells Paradox, definition of a set
Although it is related to lazy evaluation, I believe (although I could be wrong), as EJP has mentioned, short circuiting is a better term to describe this. The main reason being that lazy evaluation is much larger in scope and has further applications beyond this example. It refers to not computing values until they are needed, whereas short circuiting specifically refers to not computing values because they are unneeded.

comment Prove that zero multiplied by zero is equal to zero.
@ruakh: Oh yes, that's probably it: I'm thinking of fields.
