4. Suppose the characteristic equation of a second-order Cauchy-Euler equation has a repeated root r = c E R. (a) What's one solution of this ODE? Call this y1. (b) To find a second solution that is linearly independent from the first, suppose y2 = u · Y1, where u = u(x). Solve for u(x) and then find y2(x). (c) Show that yı and y2 are indeed linearly independent. 5. (a) Rewrite ta+Bi using Euler's Formula. (b) Construct an example of a Cauchy-Euler equation whose characteristic equation has non- real roots. (c) Solve the equation you constructed in part (b) and use the formula from part (a) to rewrite the solution in terms of real valued functions.
