| Oct 7, 2020 at 21:12 | comment | added | Algernon | You are right, I missed the fact that $S$ is supposed to be the span of $p_1,p_2,\ldots$. | |
| Oct 7, 2020 at 20:59 | comment | added | Pietro Majer | Note that $S$ is the span of the $p_k$, so there are many other converging sequences $g_n$ in $S$ (for instance $S$ could be the whole ring $\mathbb{R}[x]$, in which case the OP statement is true), so it seems more complicated (I also think it's not true, for similar reasons) | |
