As somebody used to say:

Does research. Smokes. Battles administration. Smokes. Wishes he could stop battling administration so that he could have more time to do research. Smokes some more.

The same. Except I do not smoke.

comment Prove from the definition of differentiability that the function is differentiable at 2.
There is a comment on this page which answers exactly that: "I've edited your post to show [you] how to format your equations with fractions, and how to line up several equations in a row. If you edit your post, you'll see how it works."

@user143601 "The anwser [t]here did nothing but confuse me more" Nice to know.

comment Is there a name for the trivial probability distribution P(X=x) = 1 for a unique x?
Recall that "Dirac's delta function" is actually not a function in the mathematical sense of the term and that Dirac measures are not absolutely continuous with respect to Lebesgue measure hence they have no PDF.

comment Decomposition of sum of two independent random variables
@leonbloy Quite true, but symmetry in the sense that (X,Y) and (Y,X) are identically distributed, not only that X and Y are.

comment Does this Stochastic Differential Equation have a name?
No need for a SDE, $Y$ is simply $Y_t=Y_0+at+(b/c)(e^{ct}-1)+\sigma B_t$. "Name"? No. "Explicit distribution for first passage times"? No.
