I've been a professor of mathematics at The University of North Carolina - Asheville since 1997. I've been using Mathematica since I started graduate school in mathematics at Ohio State in 1989. At that time, we used version 1.1 (as I recall) to teach calculus in our Calculus and Mathematica classes. I've used it pretty much continuously in my teaching and research since then.

In addition to my posts on SE, you can find some of my papers, teaching notebooks and other Mathematica based oddities strewn throughout my website.

In recent years, I've also worked as a part-time consultant to Wolfram Research focusing on development of mathematical content for WolframAlpha.

comment Automatically detect largest interval over which NDSolve can find a solution
@MichaelE2 You are probably right - I was clearly being paranoid. :)

comment Fill gap created by Exclusions
You're plotting two different functions and each has a reasonable choice of Exclusions independent of the other. Why don't you use to Plot command and combine the results with Show? You might also try the TrackedSymbols -> {t0,s} in your Manipulate command. Finally, with 9 questions now asked, I think it would be reasonable for you to properly format your code - it's just a matter of indenting your code block four spaces.

comment Plotting a parametric function with three input variables
@hieron The With statement is certainly not necessary but makes it super simple to extract individual plots. You can use With[{c=Pi/2},___], for example to look at that particular image. It arose because I did exactly that when trying to figure out what was going on mathematically. Clearly, this would be particularly nice, if there were more cs in the expression.

comment Can $\it{every}$ usage of While be changed into NestWhile?
In my experience, While is very easy to compile, but NestWhile is not.

comment Specifying Range of RSolve
@QuinnCulver Well, it oughtta get the whole damn thing correct, no? If you're going to use a black box, you'd better check your results and, in this case, they don't check out.

comment Specifying Range of RSolve
@QuinnCulver I tried FindSequenceFunction without success but I really see no reason to think that such an expression exists. I can tell you that the sequence converges monotonically down to $3/4$ with approximate multiplier $1/2$ but not much more.
