(Problem 1.1.1 and 1.1.3 in text). Let v = [2 , - 1] and w = [ - 2 , - 3]. Compute v + w , v - w and then draw coordinate axes and sketch, using your answers the vectors v , w , v + w , and v - w . (a) v = [2 , - 1], w = [ - 3 , - 2]. (b) v = i + 3 j + 2 k , i + 3 j + 4 k , where i = [1 , 0 , 0], j = [0 , 1 , 0], k = [0 , 0 , 1] are the standard basis vectors of R 3 . 2. (Problem 1.1.9 in text). Let u = [1 , 2 , 1 , 0], v = [ - 2 , 0 , 1 , 6] and w = [3 , - 5 , 1 , - 2]. Compute u - 2 v +4 w . 3. (Problem 1.1.31 in text). Find the vector which, when translated, represents geometrically an arrow reaching from the point ( - 1 , 3) to the point (4 , 2) in R 2 . 4. (Problems 1.2.1 and 1.2.3 in text).
