How to solve undetermined coefficients

WebSep 5, 2024 · Solution The characteristic equation is r2 − 12r + 36 = 0 or (r − 6)2 = 0. We have only the root r = 6 which gives the solution y1 = e6t. By general theory, there must be two linearly independent solutions to the differential equation. We have found one and now search for a second. WebYou do that by getting the characteristic equation r squared minus 3r minus 4 is equal to 0. You get the solutions, r is equal equal to 4, r is equal to minus 1, and then you get that …

The Method of Undetermined Coefficients

WebNov 16, 2024 · On top of that undetermined coefficients will only work for a fairly small class of functions. The method of Variation of Parameters is a much more general method that can be used in many more cases. However, there are two disadvantages to the method.
