$f_n$ be a sequence of differentiable functions on $[a,b]$ such that $f_n(x)\rightarrow f(x)$ which is riemann integrable consider the statements
$f_n$ converges uniformly.
$f_n^{'}$ converges uniformly.
$\int_{a}^{b}f_n\rightarrow \int_{a}^{b}f$
$f$ is differentiable.
we need to find out which of the statement is not true.
