comment How can I capture a rectangular area from an image?
@JunhoLee: I get that, I just meant to think about what exactly separates one element you want from another (it seems to me that almost white lines in the image might already do the trick) and then detect those characteristic elements automatically. Afterwards it is just extraction with ImageTake and proper coordinates from the detection procedure mentioned before.

I would definitely analyse the image for whitespace between the different regions you want to extract or find some other characteristic elements in your image to look out for. Once those are found it should be a simple ImageTake on the remaining bounding box.

Could you please elaborate this problem a little bit further. Right now I cannot really see what the characteristic elements that make up your regions are because your desired output is from a different page than the input example.

@Mr.Wizard: Thanks for the great job you are doing on this forum! (sorry for ignoring the no thank you rule ;))

comment Maximize[Cos[x - 1], x] is not evaluated
Well, it seems to be fixed in Mathematica 10.2 (running on OS X here).

How about just using PiecewiseExpand /@ D[BernsteinBasis[5, 3, u], {u, 2}] // Simplify?

you forgot the Square, Cos[2x]=1-2 Sin[x]^2

comment Precision and accuracy in NDSolve and NMinimize
To 5.: Numerical methods do a lot of objective function evaluations, so it would be wise to speed up the computation time for evaluating the objective function. You might want to consider compiling it.

comment Profiling from Mathematica
My issues mentioned in the comment above seem to be resolved in Mathematica 10.1. I also think that Mr.Wizard's suggestion should work in older versions, but I am not sure if I recall that correctly. Sorry for the late reply.

comment CCompile Problems
Glad it works. I do not have Mathematica running on Windows 8, so I can only check part of it.

comment CCompile Problems
I guess you do not have access to newer Mathematica versions, right? If you do, I would definitely recommend upgrading to the latest version of Mathematica.
