Derivative of step functions @JoeJohnson126 Yes, that is what I am asking. And besides that, what is derivative of any individual f (since f is a limit of functions $\lim_{n \rightarrow \infty} f_n(x)$) what is ${f'}_n(x)$ ? |

Derivative of step functions Yes, that link illustrates exactly what I mean. With the difference that where I assumed the derivative was infinite, it actually wasn't defined. And this brings me to my question: given that derivative, how can it's integral (Lebesgue or otherwise) be any other value than 0? |

Derivative of step functions The derivative of step functions. Because as I said, it seems to me that the classical approach (The one used together with Riemann-Darboux) would yield a derivative with a range of ${0, \infty, -\infty}$. |

Help in understanding integration by changing the variable And any tips on which to choose as $f(x)$ and which as $g'(x)$ or something? |

Question about continuous functions and indefinite integrals Ah, it seems that the book wasn't clear enoug. Yes there are functions that satisfy those conditions, but what I was reffering to was that there is no way of expressing it in elementary terms. And isn't $0^0 = 0$ and if not, then I can ask about $[0.5, 1]$ there still isn't an elementary way to express it. |

The accumulation points for Dirichlet's function Yes, I think you're right. I'm relatively new to Real Analysis, and english is not my native language (the books are not in english) so sometimes the terms get jumbled up. |

The accumulation points for Dirichlet's function Accumulation point, apparently in English they're also called limit points. |
