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). |

I need a function with the following behavior i.e. $\frac{a}{\ln(b+1)}\ln(x+1)$ |

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. |

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. |

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. |

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 $(\Delta u)[\phi]=u[\Delta\phi]$? |
