How to come up with a formula for converting a set of numbers? This is the sort of thing regression is good for. |

Upper Triangular Form of a Matrix I would recommend reading the Wikipedia entry on Jordan Normal Form. |

Find a pair of polynomials @AdenDong I'm glad my hint helped then :) |

Find a pair of polynomials @AdenDong Good to know. You could also just let $r(x)=1$. |

Find a pair of polynomials @AdenDong Glad to hear it! Did yours make use of the $r(x)$ polynomial? I was surprised that we didn't need it, and thought perhaps I had made a mistake. |

Find a pair of polynomials Here's what we know: $a^2=1-2a$ and $b^2=1-4b$, so any time we consider polynomials in $c$ we get some polynomial which we can always reduce to something with just $a$, $b$, and $ab$ (no higher powers). |

What exactly is infinity? @ColeJohnson Just because some things which are not real numbers have that property does not mean all things which are not real numbers do. |

Is the vector in the span? To do this, in general, I recommend checking out this previous answer. |

Number of polynomfunctions $\mathbb{Z}_3 \rightarrow \mathbb{Z}_3$ There are 27 functions from $\mathbb Z_3 \to \mathbb Z_3$. Are polynomial functions considered equal iff they have the same coefficients, or are the equal iff they are equal as functions? |

proving cauchy condensation test Actually, your $\Leftarrow$ argument needs to be slightly modified - write the string of series equalities in the other direction, since we know that the series $\sum 2^n a_{2^n}$ converges then you can ungroup the terms in the way that you want to. |
