|    A challenging nested radical integral    |

      From: samuel.thomas.blake@gmail.com              Greetings,              I was hoping the Risch-Trager-Bronstein algorithm of FriCAS and/or AXIOM would       compute the following integral in a reasonable amount of time              -> integrate((x+(4+x^2)^(1/2))^(-1/9)*(-2+2^(1/3)*(x+(4+x^2)^(1/       ))^(2/3))^(1/3),x)              Was it wishful thinking? My computer has been running FriCAS 1.3.6 for over an       hour. The answer to this integral does not require any logarithms, so it       should be computable with the algebraic extensions of Hermite reduction, right?              Sam              --- SoupGate-Win32 v1.05        * Origin: you cannot sedate... all the things you hate (1:229/2)    |
