Consider the following statements. (i) A Taylor series is a power series that gives the expansion of a function around a point a. Convergence of such series is fully understood by means of the ratio test. (ii) We must rethink what we mean by solving y′′ + y′ − y = { cos(x + 42) x ≠ 1 0 x = 1 before trying to compute a solution defined on an interval containing x = 1. (iii) Most of the...
IGNORE (i) (ii) The procedure of finding series solutions to a homogeneous linear second-order ODEs could be accurately described as the “method of undetermined series coefficients”. (iii) The underlying idea behind the method of undetermined coefficients is a conjecture about the form of a particular solution that is motivated by the right-hand side of the equation. The method of undetermined coefficients is limited to second-order linear ODEs with constant coefficients and the right-hand side of the ODE cannot be an...
Problem #1: Consider the following statements, [6 marks) 6) There is a systematic way of computing solutions to homogeneous second-order linear constant coefficient ODES. (ii) It is necessary for a function to be of exponential order in order for its Laplace Transform to be defined for some values of s.

Consider the following statements. (i) Given a second-order linear ODE, the method of variation of parameters gives a particular solution in terms of an integral provided y1 and y2 can be found.
