Can u please answer the question (G) 1. (15 marks total) Consider the real vector space (IR3, +,-) and let W be the subset of R3 consisting of all elements (z, y, z) of R3 for which z t y-z = 0. (Although you do not need to show this, W is a vector subspace of R3, and therefore is itsclf a rcal vector space.) Consider the following vectors in W V2 (0,2,2) V (0,0,0) (a) (2 marks) Determine whether...
Problem #5: [3 marks] Let u and y be vectors in R. Consider the following statements. (i) u vl = ||0|| + ||v|| (ii) ||u + v||2 = ||u||2 + ||v||2 + 2(u'v) (iii) If au + bv = cu + dv and a, b, c, and d are all nonzero then u = 0 and v=0. Determine which of the above statements are True (1) or False (2). So, for example, if you think that the answers, in the...
