Where can I see proof for this? Also a few "simple" deductions (cos idk yet) of most simple Taylor series (cos x, sin x, e^x, etc). A book with a straightforward explanation or something like that. tks in advance peter

Some functions can and some cannot. The concept of analytic function is what you need to understand. http://en.wikipedia.org/wiki/Analytic_function
