How to digest new math more quickly? I don't find it jerky, but I'm not asking for a magic solution, but several tips and tricks on how to get better. Some people are quicker learners than other people, and I try to find out why. |

Intuition for generalized complex exponentials (like $i^i$) In my Complex Analysis class. Yes, we defined it using complex logarithm. We discussed cases when w is natural/rational/irrational. So yes, I have a proper theoretical background about it, I didn't just ran into this expression clueless. But all we did before this (exponential function!) had a nice geometric/visual explanation, and I'm asking for it for this too... if it exists. |

Intuition for generalized complex exponentials (like $i^i$) Yes, I know all about complex logarithm troubles, branches and all that. I want to know are there some specific uses of this. Why bother with to introduce this? |

visual proof of the chinese remainder theorem? Patrick Da Silva: youtube.com/watch?v=XPMzosLWGHo , and here is a formal proof running with that idea: math.uchicago.edu/~may/VIGRE/VIGRE2008/REUPapers/Bishop.pdf |

What exactly are eigen-things? Few links: blog.stata.com/2011/03/09/… mathoverflow.net/questions/31838/… And there is a really interesting gif on that wiki site, if you are a visual type. |

Determinant of an $n\times n$ matrix with 5's on the diagonal and 2's on the superdiagonal and subdiagonal If you don't know how to solve the recurrence relation, check here: wikihow.com/Solve-Recurrence-Relations under ''Linear''. Concise and simple. |

Does $A^n$ is unitary imply that $A$ is unitary? Zero matrix isn't unitary. |

How to prove that $ \sum_{n \in \mathbb{N} } | \frac{\sin( n)}{n} | $ diverges? Thank you very much for this! |
