Suppose that the Wronskian of two functions f1(t) and f2(t) is given by W(t) = t^2 - 4 = det [f1(t) f2(t); f'1(t) f'2(t)]. Even though you don't know the functions f1 and f2 you can determine whether the following questions are true or false. 1. The vectors (f1(0), f'1(0)) and (f2(0), f'2(0)) are linearly independent. 2. The equations af1(2) + bf2(2) = c, af'1(2) + bf'2(2) = d have a unique solution for any c and d. 3. The equations af1(2) + bf2(2) = 0, af'1(2) + bf'2(2) = 0 have more than one solution. 4. The functions f1 and f2 are linearly independent. 5. The vectors (f1(-2), f'1(-2)) and (f2(-2), f'2(-2)) are linearly independent.
