comment NSolve won't act on very large powers
Its not about the exact integer, this gives null results too: Cases[Table[{v, NSolve[1/x == v, x]}, {v, RandomReal[10, 1000] 10^13}], {x_, {}}]

comment How to preview the notebook file in a file explorer just like the preview of pdf file
at one time I had a script set up to auto create pdf versions of every notebook. The main point for me was so that windows search would work on the pdf's. The clutter of all the extra files gets cumbersome though.

comment Use Map on a Function with two variables
aside, just do function[a_, b_] := a+b. Return is needed in mathematica very rarely and often does not behave as you might expect.

comment Exporting sharp corners in Bézier curves to pdf
my thinking is the blunt end is the mathematically correct form. To achieve that corner in eps/pdf you need to render two separate curves that are joined so that the behavior is controlled by linejoin . Sorry I don't know off hand how to do that from within mathematica.

comment Scaling the axis
If you want f[r] vs "distance along the incline" it would be 2 r/Sqrt[3] ( or I'd do r/Cos[Pi/6] )

comment Scaling the axis
maybe ParametricPlot[{Sqrt[3]r/2,f[r]},{r,0,20}]

comment Find best convex approximation of an “almost convex” function
Does this question have a 2D equivalent? It might help you formulate your criterea and solution if you could come up with a simple 2d example.
