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. (iii) It is unclear whether series solutions to ODEs even exist, and knowing about series solutions to ODEs is mostly irrelevant in applications. (iv) There is only one way to...
