comment How to find this area by integration?
are you looking for area and not volume? so surface area then?

comment Central limit theorem for distribution peak rather than mean
i couldn't get what you are asking -- the CLT does not depend on the underlying distribution of the $X_i$, it can be asymmetric or even discrete.

comment endpoints convergence after integrating/mutiplying /subtracting power series
i think for 1,2, the endpoints don't have to be checked; since it diverges for the first series, the result will diverge also unless it's a special power series, e.g. the zero function :). (4) is correct, (3) I am not sure.

comment Why are complex numbers allowed to be combine like this?
i altered your fractions on the left to give you an example of how to format, but your RHS is incomprehensible, can you alter it into readable form that is mathematiccally equivalent of the LHS to make your point?

comment Inequality involving triangle
yes, you can have an equilateral triangle -- then all inequalities hold as equalities, so $4\sqrt{3}$ is sharp
