How can I get Mathematica to simplify $\Vert\{1,\sin(t),\cos(t)\}\Vert_2$ to $\sqrt{2}$? @term-rewritica: no, you are right $\cos^2 x + \sin^2 x$ is always 1. However $|\cos x|^2+ | \sin x|^2$ is not always equal to 1. |

How can I eliminate a function in a system of PDEs, Maple-style? An even easier question would be: how can one eliminate a function in a set of ordinary differential equations using Mathematica. |

Different determinants on 2 different computers @Öskå: Eigenvalues[{A,B}] solves the problem $\det(A - \lambda B)=0$ for $\lambda$; however in a numerically stable version unlike writing down the polynomial equation for $\lambda$ and then solving it... |

Constructing a function with Flat and OneIdentity attribute with the property that otimes[a]:>a Thank you: this is exactly the problem I was suffering. In fact, I did know that Flat affects the pattern matching but I did not know that for a pattern only the attributes at the time when it is set are important and that the attributes are then stored. |

Constructing a function with Flat and OneIdentity attribute with the property that otimes[a]:>a Thanks for your question. I figured out that my example was a bit to minimal. I changed the question such that now it is clear where the infinite recursion appears. |

Constructing a function with Flat and OneIdentity attribute with the property that otimes[a]:>a Sorry for the confusion. I tried to find a minimal example and it was too minimal (and I did not see that some old Attributes were still set). I edit the question... |

Constructing a function with Flat and OneIdentity attribute with the property that otimes[a]:>a @MarkMcClure: it also does not work with NonCommutativeMultiply. NonCommutativeMultiply[a] remains unevaluated. |

Incorrect results for elementary integrals when using Integrate @Searke: thank you for the suggestion, I will do so. |
