This question might actually be more appropriate for the cs site. Nov 14 comment Absolute Value Properties Forgot about the most basic case somehow.. Jul 26 comment “Fixed $k$” in Mathematical Induction What is the justification for proving a universal statement by means of providing a proof for a single $k$? Jul 17 comment When do I use “arbitrary” and/or “fixed” in a proof? Are you confusing arbitrary and fixed with free and bound variables? Jul 17 comment “Fixed $k$” in Mathematical Induction @GitGud: Are you saying the same or opposite thing as Qiaochu Yuan math.stackexchange.com/a/46728/11444 ? Jul 17 comment “Fixed $k$” in Mathematical Induction I don't understand your answer. Jul 17 comment “Fixed $k$” in Mathematical Induction Is that the case? Why does he say "arbitrary but fixed" instead of just "let $k$ be an integer"?
