Is mathematics one big tautology? The answer is clearly yes. In computer science, one could say that the definition of a programming language, is in itself a definition of every program that could be written in it. Similarly maths could be seen as an exploration of the consequences of its axioms, the infinite space of equations and the such that can result. |

Flip another coin each time, whats the mean times required? The idea came when thinking about random numbers and how they would normally be generated inside a range, or otherwise at least be shaped in some way, for example less likely the larger the value. |

Flip another coin each time, whats the mean times required? Sorry, I'm not great at those sorts of notations. I'm aproaching this purely algorytmicly and know only the basics of numeric infinite series, there sums, that they can converge and diverge and the such. It feels as if it gets to a point where it never stops, at least in affect, but which is in conflict to the way that in no round can there be no chance of a stop. I can accept that mathamaticly it is the case. |

Flip another coin each time, whats the mean times required? How is it possible to never stop, given that at on any round there is a positive chance of stopping? |

A variable for the first 8 integers? The overline is straight here, on Windows 7 with Firefox 7. Thanks Ilmari Karonen, that makes a lot of sence reguarding ∈. I've removed the comment to which it referred because it was long, wrong and now just in the way. |

A variable for the first 8 integers? I supose even a related statement could be "n∈{0,2,4,…,14}". Mind if I edit "rn=2n if 0≤n≤7" into your answer so that we can unify this into one answer? |

one set to be another but with each element modified Thank you. $a'$ means "$a$ afterwards" or "$a$ becomes". |

one set to be another but with each element modified Given a = {true, true, false}, is the following ok to change the values in $a$? $a'(0.8) = true$, $a'(0) = false$. Also, I'd prefer to avoid the part in your example that appears as if $f$ to the power of -1 is being calculated. |

one set to be another but with each element modified Sorry if this is obvious, is it also correct as f(0.8) = true, f(0) = false? Perhaps $a$ is a list and not a set because its entites are ordered and it contains duplicates? |

one set to be another but with each element modified I didn't understand any of that image link tomasz. |

one set to be another but with each element modified the '$b =$' line should work with any $a$, not just this example $true, true, false$. |

one set to be another but with each element modified Create like $a = 4$ or $a = b$ if there was no $a$ before that definition. What do the [] represent? |
