(5) (after 2.3) (Geometry Question) Consider the infinite system of linear equations in two variables given by ax + by = 0 where ( a, b ) moves along the unit circle in the plane. (a) How many solutions does this system have?
(b) How many linearly independent equations in the above system give you the same set of solutions? Write down two separate such linear systems, in vector form.
(c) What happens to the infinite linear system if you add to it the equation 0 x + 0 y = 0?
(d) What happens to the infinite linear system if one of the equations slightly perturbs to ax + by = c where c is a small positive number?
(6) For each of the situations described below, give an example (if it’s possible) or explain why it’s not possible . (a) A set of vectors that does not span R 3 . After adding one more vector, the set does span R 3 .
