Probability of running out of tosses you are using $n$ with two meanings: the number of tosses and the probability of the first toss (1/n). Could you clarify? |

How to check if a function is minimum to functional? No, you can find a counterexample with a $C^2$ function (just smooth out the angle point) |

Brachistochrone problem You should see that if a sequence of functions approximates a function with a vertical part, then the functional approximates the cost of the curve with the vertical part. |

Brachistochrone problem First of all: how do you prove that your solution is the minimum among functions? |

Brachistochrone problem If the curve is not differentiable how can you define the motion of the point? The velocity is constrained on the tangent line... |

Is this a valid proof to show $\frac{n^5}{2^n}$ diverges? $n^2 > 2^n$ is false for large $n$ |

answered | Give an example of a function $f$ that is differentiable at $x=a$ such that $f'(a)\ne0$ but yet $f$ attains a relative extremum at $x=a$. |

How to minimize the length of a curve on $S^2$ This is a difficult task, you should explain what are your knowleges. Are you studying for some course? |
