# Hw5 ex1 - norm minimization

From MurrayWiki

**Q** How do we solve the minimization problem for ?

**A** The minimization of the square root of the norm is difficult, but it's doable by just taking the derivative of the function; though one will have the same result by minimizing just , where with this notation we mean .

Note that in the literature, is generally already defined as .
