Comments on Sheet 5 When working in , make sure you really are working in : -3 = 0 = 3; -2 = 1 = 4; -1 = 2 = 5 In particular, you can’t divide by zero, even if it’s disguised (e.g. as 3, -3) Confirming the basis using REF only works if you choose the furthest left of the suitable basis vectors. (Other bases are available) 1 2 +

Comments on Sheet 5 Be careful working with infinite dimensional vector spaces: a lot of the results in the course only apply to finite dimensional vector spaces E.g. (3.2.3) – see proof E.g. (2.4.2) – the definition of a basis is given in terms of an infinite independent set is an infinite set in which every finite subset is independent. which implies there is no finite maximal set, so no finite basis.

**Warm-up Questions Q1: Q3 Find a basis for the column space of A.**

Find a basis for the row space of A. Find B, C such that A = BC. Q3

5
**Overview of Sheet 6 Q2: similar to Q1 Q4: Q5:**

(i) consider , use result from Q3 (iii) uses result from Q3 also Q5: (i) use standard matrix results, don’t try to write out the whole matrix. (ii) & (iii) start by doing the calculations, which should give you some idea where to go.
