Label each of the following statements as true or false. If true, prove the statement. If false, provide a counterexample. If a proof or counterexample is not provided, this exam may be marked "Incomplete." (a) Cauchy-Euler equations have unique solutions at x=0, specifically the function y = 0. (b) Solutions to second-order Cauchy-Euler equations with repeated roots of the characteristic equation are linearly independent. (c) Solutions, if they exist, of equations of the form an (x)y(n) (x) + an-1(x)y(n-1) (x) + a1 (x)y' (x) + ao(x)y(x) = f(x) are completely described by n linearly independent func- + ... tions.
