1. The problem statement, all variables and given/known data For u=(26, 6, 21) and v=(−27, −9, −18) , find the vectors u1 and u2 such that: (i) u1 is parallel to v (ii) u2 is orthogonal to v (iii) u = u1 + u2 2. Relevant equations None 3. The attempt at a solution I'm quite lost on this question and not sure how to even start. Can someone explain the question and give me some hints to get started? Thanks in advance.
