WebOne of the steps was this (let u and v be vectors and let u + v mean the norm / magnitude of u + v): line 1: ‖ u + v ‖ 2 − u − v 2 line 2 := 2 u v − ( − 2 u v) line 3 := 4 … Webvector v1 that lies in the latter null space, but not in the former. We can always take v1 = e1 = 1 0 =⇒ v2 = (A− 3I)v1 = 2 2 , but there are obviously infinitely many choices. Another possible choice would be v1 = e2 = 0 1 =⇒ v2 = (A −3I)v1 = −2 −2 . 4. Let A be a 3 × 3 matrix that has v1,v2,v3 as a Jordan chain of length 3 and let B
