Homework 9, due Friday November 4th , in class 1. Suppose x 1 , x 2 , and x 3 are linearly independent vectors in R n . Define y 1 = x 1 + x 2 , y 2 = x 2 + x 3 , y 3 = x 3 + x 1 . Are y 1 , y 2 , and y 3 linearly independent? Prove your answer. 2a. Are the vectors v 1 = ± 2 1 ² , v 2 = ± 5 3 ² , v 3 = ± 7 - 3 ² linearly independent? 2b. Write v 3 as a linear combination of v 1 and v 2 . 3. Find the coordinates of the vector 3 2 5 with respect to the ordered basis
