      b630b449       Per       https://math.stackexchange.com/questions/2230651/a-conjectured-c       ntinued-fraction-for-phi-phi       integrating from 0 to infinity of the function:              e^(-x*(2+(1+sqrt(5))/2))*(cosh(x)+sqrt(5)*sinh(x))^((1+sqrt(5))/2)              is supposed to be:       (phi^phi - 1/phi)/2       where phi =(sqrt(5)+1)/2              Maxima can't find this result symbolically, but numerical integration gives       the expected result.              What about other computer algebra systems?              --- SoupGate-Win32 v1.05        * Origin: you cannot sedate... all the things you hate (1:229/2)    |
