comment Integral of sum of sequence of integrable functions
If $f_n$ non-negative using Monotone Convergence Theorem we have $\int {\sum {f_n}}=\sum {\int {f_n}}$.

comment Positiveness of Limit Superior
i mean, since we cannot assume the continuity of $f(t)$, we cannot assume the continuity of $f(t)/t$, so function $\int_x^1 \frac{f(t)}{t} \mathrm dt$ may be discontinuous at some point in $(0,1]$. in this case the expression $\frac{d}{dx}\int\limits_x^1\frac{f(t)}{t}dt$ will be meaningless.

since we don't know the continuity of $f(t)$, as a function of $x$ can we assume that $\int_x^1 \frac{f(t)}{t} \mathrm dt$ has derivative?
