The limit of a recurrence relation (with resistors) Thanks for that. Is $\large \lim _{n \rightarrow \infty}(\frac{F_{n+1}r^2+F_n rR}{F_{n-1}R^2+F_n r})$ computable directly? |

What's the proof that the Euler totient function is multiplicative? Thank you- at long last it's clicked! |

Functions satisfying $f(m+f(n)) = f(m) + n$ @DejanGovc Thanks; that's really quite elegant. |

Functions satisfying $f(m+f(n)) = f(m) + n$ @DejanGovc, could you explain why the usual argument claims $f(x)=cx$ is the only class of solutions to the rational Cauchy's functional equation? |

Intuition behind $\nabla \times \mathbf{F}$ Thanks for your patience! I thought it was the dot product (perhaps add that to the answer in case dullards like myself might benefit from it). |

Intuition behind $\nabla \times \mathbf{F}$ Why not just evaluate $(\nabla \times \mathbf{F})(x_0,y_0,z_0)$? |

Intuition behind $\nabla \times \mathbf{F}$ Excellent answer (as far as I can tell), by the way. |
