The rank of the matrix A is its most important property. There are many equivalent ways of characterizing the rank: rank(A) is the number of pivots in an echelon form of A rank(A) is the dimension of the column space and row space of A rank(A) is the size of the largest set of independent columns of A PART A) Let u be a vector in R³ and A is a 3 x 3 matrix with columns v, 2v, 3v. What are the possible values for rank(A)? Justify your answer. PART B) Let u, w be vectors in R³. Let A be a matrix with 4 columns v, w, 2v+w, vw. What are the possible values for rank(A)? Justify your answer. (Hint: for this question you may want to consider the third characterization of rank listed above)
