Hi,
Please forgive me if sometimes my questions seems a bit simple.
I'm only self taught and researching by myself. But I did manage to derive some new published material, and my questions are real research questions. I just don't have anyone else to ask.

can you express it in terms of max/min? |

I dont understand where $f$ comes into the picture |

so maybe I didn't get it.. doesn't Dirac and Heavyside discontinuous? |

Hint: $g$ is continuous. |

Thanks for your help! Unfortunatly, this doesn't work as well. Here's my code: #include <iostream> #include <cmath> using namespace std; long double phi(long double x, long double n, long double t = 2) { static long double pi = acos((long double)-1); return sin((n+.5)*pix/t)*sqrt(t*2.)/(pi*(n+.5)); } int main(int, char*) { long double sum = 0, x=.8,y=.3; for (long double n = 1;n< 100000;n++) { sum += phi(x,n)*phi(y,n); if (((int)n)%1000) cout<<n<<' '<<sum<<endl; } return 0; } |

wow that's amazing. you actually got $ \min(x,y)=\sum_{n=1}^\infty n^{-2}\sin nx\sin ny$? |
