How many decimal places are needed for incremental average calculation? @JernejJerin If you are satisfied with the answers, you might consider accepting them, else you might want to indicate what more information you want. |

Good problem book on Abstract Algebra I unaccepted your answer and instead accepted Dedalus's answer since on retrospective, I have found some of the book Exercise in Algebra and other books a more concentrated source of problems. I hope you don't mind. |

Determinant of a Modified Jacobian of a Function That's all there to it?! I came up with a similar but infinitely cruder solution, however, I was not sure of this. Also, I was thinking there might be some rank-related solution also. Anyway, thanks. :-) |

How to solve this equation:$\sqrt{x-\sqrt{x-\sqrt{x-\sqrt{x-5}}}}=5$ @vesszabo No, he uses it in this direction, but goes upto infinity, however, I am not sure of the formal justification of the step. |

How to solve this equation:$\sqrt{x-\sqrt{x-\sqrt{x-\sqrt{x-5}}}}=5$ The logic is similar to $\sqrt{x-5} =5 \implies \sqrt{x-\sqrt{x-5}} = 5$ |

Dual basis of a shrinking unconditional basis @TrzyTrypy You can delete the question yourself and that would be the best method to do so. |

Cycling Digits puzzle @PerManne Yup. Sorry about that, I was going to update it. |

Existence of $\vee$ or $\wedge$ for non-monotonic functions But, we first show that there is atleast one, and then prove for all from that single one. About strict inequalities, I guess, whenever there is equality, we get a constant function. |

Existence of $\vee$ or $\wedge$ for non-monotonic functions @JasperLoy I removed the continuous function thing, since it was superfluous. Anyway, I have not fixed $a,b,c$, Since, if the first two options from the list are not satisfied anywhere in $R$, then either of the other two options (the third one, and then the original assumption) must be satisfied, then I pick one of them and use it to show that, it applies all over the domain. Because, next you can select another point $e$ and do the same thing as has been done with $b,c,d$ to get the same relation with $c,d,e$ and so on. |

field generated by a set Where I mean $K$ by $G_{S}$ |

field generated by a set @JasonDeVito I guess your objection is invalid, since we are talking about $S$ generating $R$, rather than $S$ being $R$ itself. Since, if $\frac{1}{10} \in S$ then $\frac{k}{10} \in G_{S}$ where $k \in Z$. |

field generated by a set @FortuonPaendrag You say that your proof is flawed. I think it would be good if you can probably indicate why do you think it is flawed in the answer itself. |

In what spaces does the Bolzano-Weierstrass theorem hold? @KevinCarlson Its okay. I do not mind. |

In what spaces does the Bolzano-Weierstrass theorem hold? I guess not. So, basically, we want to find conditions for total boundedness and completeness from the metric of the space and the set of points? Is this true? |

In what spaces does the Bolzano-Weierstrass theorem hold? @KevinCarlson Okay. If I say that total boundedness of a closed subspace of a complete metric space implies compactness and vice-versa. Will that address the question enough? |

How to Find a Finite-Difference Matrix You might want to learn more about the finite difference methods. I am sure there are enough textbooks on the same that explain the process in detail. |

Non surjectivity of the exponential map to GL(2,R) Try $A = \left(\matrix{1 & 0 \\ 0 & -2}\right)$. And show that this cannot be an exponential, since exponential cannot be negative in $\mathbb{R}$. |

Sequence of convex functions @LVK Okay.Thanks. |

Sequence of convex functions @LVK Why are we not considering infinity? Why only real values? |
