Comment #3 on issue 2740 by [email protected]: Some Poly docstrings should be
moved out of the internals
http://code.google.com/p/sympy/issues/detail?id=2740
I also add, that for many methods [1] we should have the proper "See Also"
section.
I also add here some remarks about the main article [2]. May be open a
separated issue for it.
When user begins to lean polynomials, he expected become familiar with main
interface of polynomial, what it is, and only then read about how
manipulate with them and basic operations.
while this document immediately starts with a description of "Basic
functionality" of something something undefined.
I would like to read about the main properties of Poly, which I can use:
1. That we can use ordinarary sympy expression and use helper Poly. How
they related on the polynomial module.
2. That Poly can be constructed from expr and has .as_expr()
3. That main info which Poly can provide is :
* degree()
* nth() (to this method, I got with great difficulty!)
* LC, EC, TC, LT, ...
* domain, and what is this, shortly
* free_symbols (free_symbols_in_domain)
* exclude
