This is a routine minimization problem, find the closest point or points to b = (-1,2)^T that lie on (a) the x-axis and (b) the line y=x.(adsbygoogle = window.adsbygoogle || []).push({});

First I am supposed to solve it with the Euclidian norm, which is no problem, but then we are supposed to solve with the [tex]L_\infty[/tex] norm. I am a little confused because the [tex]L_\infty[/tex] is the max of all points, so it is asking to minimize the maximum point?? :uhh:
