determining orthonormal matrix of rank N with special first row yeah, I had thought of that (see my answer) unfortunately I'm looking for real-valued matrices. |

determining orthonormal matrix of rank N with special first row I'm familiar w/ Householder reflections: is there an easy way to get the normal vector n from the two vectors "v" and "w" as you described? |

determining orthonormal matrix of rank N with special first row +1, thanks. (p.s. this isn't meant as a criticism, but I am amused by the difference between programmer + mathematician mindsets: "solved" in math circles seems to be proof of existence, "solved" in programmer circles is a description of an algorithm) |

determining orthonormal matrix of rank N with special first row ah-- thanks! so you have to escape the \\\\ symbols. |

Finding an angle within an 80-80-20 isosceles triangle the berkeley link is kind of confusing... but +1 for the name as a key to searching! |

good online resources for 2nd-order system dynamics the problem is there are a lot of mediocre pages out there, and I'm looking for a good one; most of the sources of this type of information just have the transfer function with 1 in the numerator and something in the denominator. (having said that, the one you posted isn't too bad) |

How to solve this trigonometric inequality: $k \sin(\frac {\pi x} {2})\cos(\frac {\pi x} {2})>0$? @AndrejaKo: Ah, that kind of sausage. Yes, we tend to use it in the context of politics + shady manufacturers. The terminology is a bit different, though; not sure how to correct + keep the colloquialism. I would probably replace "sausage" with "expression". Less flavorful but clearer. :-) |
