revised The area of trapezium is given by $A=(a^2-x^2)(x+a)$. Find x for the area to be a maximum and find A max.
fixed latex, also this is not abstract algebra.

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.
