Here we post solutions to problems presented to us via our online students, or via the Help Line (we post these as often as our workloads will allow).
Allthough we don't necessarily know the source of these problems, we guarantee the solutions are entirely ours! In order to give you the opportunity to try the problem for yourself, solutions are hidden from view initially, but they can be accessed by clicking on the response icon or activating the video link to YouTube.
