Hw5 ex1 - norm minimization

Q How do we solve the minimization problem for \(\sqrt{ || \dot{x} ||}\)?

A The minimization of the square root of the norm is difficult; though one will have the same result by minimizing just \(|| \dot{x} || \), where with this notation we mean \( \dot{x}^T \dot{x} \)
