Take an m x n grid, and in each box pick two opposite corners at random to connect. What can be said about the resulting pattern? Found the problem, it was on my side, sorry for the trouble... |

Convergence of series $\sum\limits_{n=0}^\infty\frac{3n}{n!}$ You have to be careful when $n=0$. Also your assertion that "the sum is the same since $n\to\infty$" is incorrect - it does converge similarly, but not to the same value... |

Finite-state machine. Try to make a separate state for encountering a "b" and then within that state to detect if you are the next-to-last or not. How do you do that? |

Finite-state machine. Well, what are the states you want your machine to have? Clearly you want to detect "b" and then wait to see if you are in the penultimate character or not. Please try to set it up, or ask for more hints. |

How do you verify that a function is the inverse of another function? That's the definition, It does work when you can actually calculate :). A way to get a ballpark is to see if the graphs of $f$ and $g$ are a reflection of each other around the line $x=y$. |

Proofs by Contradiction (cont.) one natural class is the proofs where you pick a maximal element with a certain property and then contradict optimality, like the claim that integers are finite -- pick the maximal element $x$ then $x+1$ is also an integer... |
