Supremum of continuous functions is continuous? What is $H^1(\Omega)$? Forgive my lack of knowledge of functional analysis. |

Maximum absolute deviation Dear Juan, you really need to work on your mastery of the English language if you want useful comments. Many of your questions are hard to understand, and I, for one, do not understand what you want from us in this question. Could you rephrase it? |

how to make a matrix a magic square? There are many "matrix problems". Could you change the title to something more useful, such as "how to make a matrix a magic square" |

Algebra question resubmited @DavidMitra: only because of the later edits by Crete and amWhy after my comment, and the question is still not clear to me. |

Differential Equation Well yes, that clearly is your question, but what approach are you trying, because I don't think this is very clear from what you wrote. |

Differential Equation In that case, what are you trying to do (in terms of equations)? |

Calculating a function limit What have you tried? What actually is your question? |

Differential Equation So... what exactly do you expect from us? Just the answer? Or is this homework, and do you want a hint? |

Algebra question resubmited Your previous question was closed. This is a literal copy. Why did you think it wouldn't get closed this time? |

Prove that s is finite and find an n so large that $S_n$ approximate s to three decimal places. @rlgordonma: I didn't want to completely give it away, but yes, that is closer to an answer :). |

How can I systematically find the roots of $ x^4 + 1?$ Is there some algorithm? Better. Although I'd simply expect this question to be closed as duplicate. |

How can I systematically find the roots of $ x^4 + 1?$ Is there some algorithm? Yes, those answers are much better and more welcoming. This just smacks an answer to the question, which is technically correct, but the techniques it relies on are not explained at all. |

How can I find $\sum_{k=1}^{1233}f(\frac{k}{1234})$ I like how you can solve for $f(1/2)$. |
