ABSTRACT
This result of course agrees with physical reasoning. For practice, you might want to use this method to find a1 (0+) for this example; we earlier found by physical reasoning that this was 0.
We have used some simple simulation methods earlier in the book, so the idea is by now not entirely strange to you. In this section we take a more organized and comprehensive viewpoint, rather than just showing specific examples. While analog simulation is, as a general-purpose analysis tool, today largely obsolete, it still finds occasional application in special-purpose contexts, such as built-in equipment in machines or processes. For this reason and also for historical interest, we begin with a quick overview of this technology.
