[WPI] [cs2223] [cs2223 text] [News] [Notes] [Recurrence] [Solving]
In contrast to the pages for Step 1 and Step 2, this step is exceedingly simple. Add the homogeneous and particular solutions. Here are some Examples:
Note, in this example, that the last two terms cannot be combined (they do not give the same values!) so there is no potential repeated-root problem.
Note that this is just the geometric series
Now we're ready to determine the undetermined coefficients by using boundary conditions or initial conditions, in Step 4.
