comment Uniform distribution and expectation
@Dee Chantelle: you can't find an easy anti derivative so it's probably what the problem is asking for. You can express the integral in terms of the Erf error function integral but not much more.

comment A problem related to integration in $L^1$
@Gary: Surely you mean $m(E)<\epsilon$, as per Lusin's theorem.

comment Limits of complex line integrals as the Radius goes to infinity
Hint: for 1, write $z=Re^{i\theta}$ and $dz=i R e^{i\theta}$ so that the fraction scales like $\frac{R}{R^2}=1/R\rightarrow 0$.

comment Using Feynman-Kac, compute the following:
A good first step is to actually write down the Feynman-Kac formula as it applies to your expectation. See here: en.wikipedia.org/wiki/Feynman–Kac_formula

comment $\mathrm E [X \mid X=x] = x$?
@Math1000: it is perfectly well defined as that is the entire point of the measure theoretic definition.

comment The sequence $f_n=x^n$ is not weakly convergent in $C[0,1]$
@reuns: If you have an answer to this question, please post it. Also note that the OP is asking about weak convergence.

comment Instructive examples of independent sets on a probability space?
This question is way too broad. Try to at least make it more specific like maybe asking what are examples of random variables that are non-obviously independent.
