Strange thing, is that my first approach up above works for me. Anyway I will look into it some more later on.
Degree is not a function--rather it is a parameter. So you do not want Degree@, (i.e., no @) and also yo want to divide by Degree in your definition of degree as in the following: Manipulate[ With[{degree = \[Phi]/Degree}, ...
They are GIFs rather than MathJax. And presumably the Gif generation is substandard suddenly for some reason. They should be MatJax, I feel, at least for those cases that support it.
The e is the result of the evaluation in the argument of Reap. The reason for the extra set of braces in {{a,c,d}} is that for what was Sown, Reap returns a list of lists--in this case there is only one, but this allows for the other argument...
A useful starting point is any of the code included with the notes section associated with the main section that you are reading.
Your manipulate is trying to keep track of the symbols Subscript[x, b] andSubscript[x, s] which are not changing. The way to make Manipulate stop looking at those is to use the TrackedSymbols option to tell it what to really pay attention to as in...

Thanks everyone!
Here is a way to plot the time of sunrise (in minutes after midnight) on the first of the month in 2015: DateListPlot[ Table[With[{time = DateList[Sunrise[{2015, i, 1}]][[4 ;;]]}, {{2015, i, 1}, time[[1]] 3600 + time[[2]] 60 +...
What is ZeroZeta? It is not a function in the standard Mathematica distribution as far as I see... But ZetaZero is and it gives In[1]:= N@ZetaZero[3] Out[1]= 0.5 +25.0109 I
