Unformatted text preview: The generalization of the Wronskian is given on page 221. It is used as in the last Chapter to show the linear independence of functions, and in particular homogeneous solutions. For the situation where there are constant coefficients, you should be able to derive the characteristic polynomial, and the characteristic equation, in this case each of n th order. Depending upon the types of roots you get to this equation, you will have solution sets containing function similar to those in the second order case. (Examples 24, p. 227229) The general solution of the nonhomogeneous problem easily extends to the n th order case. (Equation 9, p. 225) Both variation of parameters, and the method of undetermined coefficients generalize to determine particular solutions in the higher dimensional situation. (Example 3, p. 234; Example 1, p. 239) Relevant Applications: Double and multiple spring mass systems...
