Oct 30, 2016 at 12:53 | comment | added | Willie Wong | By contradiction, suppose $p$ is in the interior of the ball and attains the maximum with $\nabla f$ in the direction $v$. Take the line through $p$ in the direction $v$ and look at the restriction of $f$ on the line. You reduce to the 1D problem. | |
