Let $f ( x ) = \min \{ 1,1 + x \sin x \} , 0 \leq x \leq 2 \pi$. If $m$ is the number of points, where $f$ is not differentiable and $n$ is the number of points, where $f$ is not continuous, then the ordered pair $( m , n )$ is equal to\\
(1) $( 2,0 )$\\
(2) $( 1,0 )$\\
(3) $( 1,1 )$\\
(4) $( 2,1 )$
