I think I'm finally understanding this stuff :) Apr12 comment Don't understand how to start with this assignment questionIt seems like I'm supposed to do the formula in general, I guess in that case I can just assume, like you said, that f(x) and its derivatives are constant? Also could you clarify what you mean by agree/disagree?

Jan30 awarded Scholar Jan30 awarded Supporter Jan30 accepted Need help understanding matrix norm notation Jan30 comment Need help understanding matrix norm notationSo $Ax$ would be, in a general case that max non-zero vector? or one of the vectors in A? I just don't really understand how $Ax$ and $x$ are related, I guess. Jan30 asked Need help understanding matrix norm notation Mar29 comment How to change degree of elements in a fieldThanks! Exactly what I needed to know, also: wicked shortcut, really great way to re-think the problem. Mar29 comment Need help understanding finite fields / modulo for polynomialsThanks everyone, really helpful stuff - learned more tonight than in the last two months of lectures. Mar29 asked How to change degree of elements in a field Mar29 comment Need help understanding finite fields / modulo for polynomialsThanks @AndréNicolas - so is the $\mathbb Z_3[x]$ just referring to the modulo of the coefficients then? I'm trying to wrap my head around how to generate a finite field from a statement like $\mathbb Z_3[x]$ / m(x) Mar29 comment Need help understanding finite fields / modulo for polynomials@J.D. I understand how to do polynomial long division, but am kind of confused on how it differs when in $\mathbb Z_3[x]$
