The vectors e1 = are called the elementary vectors in r2. (a) find all solutions c1, c2 such that ciei + c2e2 = 0. (b) show that any point (i.e. vector), (2, y), in r2 can be written as a linear combination of ej and e2-in a rather obvious way. question 2. now consider the vectors u1 = ( 1 and us = [ -1 ]: (a) find all solutions c1, c, such that cu + cu2 = 0. (b) show that any point (i.e. vector), (x, y), in r2 can be written as a linear combination of u and u.
