of functions with derivatives of all orders in R. Assume that the linear transformation D = d.x * satisfies: Dg = 2g + h Dh = g+h a) Find the differential equation D² f + aDƒ + ßf = 0 that functions in V must satisfy. b) Find the matrix A of D in this basis. c) Verify that for the scalars a and B that you found: A² + aA+ BI = 0. Hint: Both g, h need to satisfy the differential equation. Use the informa- tion about Dg and Dh which is written in terms of g, h to try to find the differential equation that must be satisfied.
