 Oct 18 revised If $(a + ib)^3 = 8$, prove that $a^2 + b^2 = 4$ Format the tag properly Oct 18 suggested approved edit on If $(a + ib)^3 = 8$, prove that $a^2 + b^2 = 4$ May 19 awarded Citizen Patrol May 4 awarded Good Answer Feb 5 awarded Yearling Dec 12 suggested rejected edit on If p is an odd prime, prove $1^p + 2^p + 3^p +\cdots+(p-1)^p$ is congruent to $0\pmod p$ Dec 9 comment 7 Drinks - 7 Flavors - Infinite variety? Well, no. For the same reason that the Banach-Tarski paradox doesn't apply to reality (you can't have an infinitesimal part of a ball/amount of a liquid). Sep 19 comment Solving Normal Distribution Probability Aug 25 comment I need a function with the following behavior i.e. $\frac{a}{\ln(b+1)}\ln(x+1)$ Aug 19 comment Create a C++ program to evaluate the following series: $\sin x \approx x - \frac{x^3}{3! }+\frac{x^5}{5!}-\frac{x^7}{7!}\cdots\pm\frac{x^n}{n!}$ Since we're talking C++, some template metaprogramming could speed up the calculation as well. Aug 8 accepted The distribution $\Delta u$ (where $u = \ln|\vec{x}|$) Aug 6 comment The distribution $\Delta u$ (where $u = \ln|\vec{x}|$) I guess I was using it as a definition without realizing. I have removed that sentence from the question to avoid more confusion. Aug 6 revised The distribution $\Delta u$ (where $u = \ln|\vec{x}|$) deleted 97 characters in body Aug 6 comment The distribution $\Delta u$ (where $u = \ln|\vec{x}|$) There's no explicit definition in the exercise, but just expanding $\Delta$ and applying the known relation $\partial u[\phi] = -u[\partial \phi]$ means it has to be that way. Aug 6 awarded Commentator Aug 6 comment The distribution $\Delta u$ (where $u = \ln|\vec{x}|$) @joriki: I added the missing $\sin\theta$ factor. Are you saying that I should apply Green's identity to the two integrals instead of using it to show $(\Delta u)[\phi]=u[\Delta\phi]$?
