comment What do $\gg$ and $\ll$ mean?
This is language dependent. In ruby the "<<" is the append method for an array: [1,2,3] << 4 gives [1,2,3,4]

comment Rigorous way to find the limit of this difference?
Hint: suppose the given angle were 90 degrees, and the angle between r and s were "a". Then you would have "r = scos(a)" As r and s increase without bound, a tends to 0, so cos(a) tends to 1, and you have r = s, so "s - r" tends to 0. Now drag out the law of cosines and see what happens given one angle at 110 and one side fixed at 1.

comment Why isn't the 3 body problem solvable?
All of which leads to the curious, and unanswered question, is the solar system stable?
