comment Polynomials vs polynomial functions
And the elements of $R[X]$ are in no way functions, so we can't write $f(x)$ for $f \in R[X]$?

comment Polynomials vs polynomial functions
@GitGud So a polynomial function is determined by the values it takes when evaluated in the domain of the function, whereas a polynomial is determined by it's coefficients?

@ChristianBlatter What would be a less condensed way of writing this? I'm interested to know where the notation comes from.

comment What was the first bit of mathematics that made you realize that math is beautiful? (For children's book)
@Cruncher which is zero. $\lim_{n \to \infty} 10^{-n} = 0$, as does $\lim_{n \to \infty} 10^{-n} b$, which corresponds to any $0.000...b_0...b_n$, where $b_k$ is the kth digit of the decimal expansion of b.

comment Definition of homogeneous ODE
I wish they'd explain this to us, some of our lectures notes are really quite sloppy in areas, mostly with the more applied modules. Thanks anyway :)

comment How do I prove a basic and obvious-looking set relations?
Wouldn't we have to prove it from some axioms of propositional logic?
