 Jan 15 awarded Yearling Dec 26 comment On “familiarity” (or How to avoid “going down the Math Rabbit Hole”?) An elegantly succinct and informative answer using analogies from computer science! Kudos to you! Dec 9 awarded Popular Question Dec 9 awarded Popular Question Nov 18 comment Incremental averageing Can you elaborate on why precision errors are smaller in the second expression? Does the first expression contain a subtraction of nearly equal values? Sep 4 asked Verifying an integral identity related to asymptotic homogenization of an elliptic partial differential equation Sep 1 accepted Interpreting a singular value in a specific problem Aug 20 asked Interpreting a singular value in a specific problem Aug 20 accepted Explaining the physical meaning of an eigenvalue in a real world problem Jul 31 comment Obtaining a bound on the differential operator This almost makes sense. But the left hand side of the inequality uses $\frac{du}{dy}$, not $\left| \frac{du}{dy}\right|$. Unless it is somehow implicitly assumed that $\frac{du}{dy}>0$, I just can't see how we can conclude this.
