(1) Determine whether each set of vectors is linearly independent or linearly dependent by the method given: 0 Inspection: By observing and thinking about the vectors, you can determine if they are independent or not. Provide a one or two sentence justication and any pictures you deem helpful for understanding {if you wish; pictures are not required}. 0 Algebra: Explicitly nd all the linear combinations of vectors which yields the zero vector and tell whether the vectors are or are not independent. How to do this {while you know how to do this, we never did this explicitly in class): 1. Form an augmented matrix with columns equal to the vectors and augment column of zero 2. Row reduce to RREF If nonzero solution (incl. many solutions or no solution} exists > linear dependence If only zero solutions {unique solution with all zeros in augment column) exist > linear independence (a) Algebra: 1 3 5 do = 2 (1.1 = 2 *2 = 2 3 I 1 I Homework Assignment #5 2 (b) Inspection: 1 4 10C| do = 2 J] = 8 d2 = 2m 3 12 30C| (c) Algebra: 3 1 '1 do = 1 51 = 3 *2 = 1 1 0 0 (d) Inspection: l _ 2 a _ 7 gm _ 1 a1 _1 (1'2 = any other vector (e) Algebra; 1 8 '4 - _ 2 - _ 4 ~ 2 D 3 a1 _ 2 2 2 4 1 4 (2) Compute each vector below.
