 Apr 8 revised Computing the inverse error function added 6 characters in body; added 2 characters in body Apr 8 revised Computing the inverse error function added 147 characters in body Jan 20 revised Prove that the preimage of a prime ideal is also prime. I REALLY hate the 6 character limit on edits, especially on a math site, where each character matters. Dec 3 revised Minimizing Frobenius norm of a special type added 580 characters in body Nov 12 revised What is the relationship between prime ideals and their generators? added 105 characters in body Nov 8 revised How do I show a mapping is a homomorphism? typo Apr 24 revised When does something become a “mathematical object”? added 983 characters in body Apr 22 revised Perpendicular versus perpendicular bisector The [tag:geometry] tag should not have been removed. Apr 22 revised Algebra problem stumping me added 22 characters in body Apr 22 revised Algebra problem stumping me Better tags Apr 22 revised Algebra problem stumping me added 132 characters in body Apr 20 revised Number of necessary stickers to complete a sticker album Attempted to rearrange things to help the OP end up with an easier to read question. Apr 19 revised Prime factorization of 1 @ncmathsadist I think adding "unique" is a significant contribution to your answer. Apr 14 revised How does the base of a group determine the “sort” of the elements in the group Added more examples. Apr 10 revised Let $A,B$ be two subsets of a finite group $G$. If $|A|+|B|>|G|$, show that $G=AB$ Corrected the answerer's confusion between sets and the size of sets. Mar 4 revised Differentiable function with bounded derivative, yet not uniformly continuous Since the derivative is not continuous and depends on the point x, I changed f' to f'(x) in two places. Mar 1 revised Differentiable function with bounded derivative, yet not uniformly continuous added tags Sep 28 revised Surprising identities / equations Added the parentheses for the cosines to improve readability.
