I am a retired software developer. I retired at the end of 2003 and since then my computer programming activities have been for recreational purposes. I find Mathematica excellent for that.

I started using Mathematica in 1997 (Ver. 3). I am currently using Ver. 9. Although I have used Mathematica for all kinds of stuff, I use it mostly to pursue my long standing interest in Euclidean geometry, both in the classical Greek synthetic form and in the more modern analytical form.

17h	comment	How to extract data of large function Your example doesn't shed much light on your problem since it is too simple to produce the problem of not being able to save it in closed form. Saving a table made with `Table[{x, f[x]},{x, Range[0., 0.5, 0.1}]` would save the information needed to do a `ListPlot` that would work for your example, but I can't decide from your question whether or not it work for your real problem.
18h	comment	How to extract data of large function This solution has a problem. It preserves the range data at the expense of the domain data. I think the OP needs a solution the preserves both.
