How is $dx \over dy$ different from $\partial x \over \partial y$? But for all mechanical purposes all the same rules apply in both cases? We are asking how the "numerator" variable varies with respect to the "denomiator" variable, assuming everything else is held constant. |

How is $dx \over dy$ different from $\partial x \over \partial y$? So what does $dx \over dz_1$ mean? Or is it undefined? If it is undefined why not just use the same notation? |

Generously Feasible? Can you provide the link? It doesn't show in my search results? |

Counting Hexagons in Triangle Grid Recurrence? This is correct, thanks. I was fooled by the N=4 case into thinking that all hexagons that touch all three sides must have one side of n-2, which is true for N=4 but not true for higher values of N. For example for N=5 we can have a hexagon that results from chopping off triangles of side 2 removed from each corner of the grid. |

N unlabelled balls in M labeled buckets This proves it incorrect, however I still don't see what went wrong in my reasoning. The number of ways to put N labelled balls in M labelled buckets is $M^N$ correct? So why can't I just divide by the number of permutations of N balls to arrive at the unlabelled ball case? |
