Poxa gente desculpem mas coloquei um sinal errado. Na verdade era
int (tdt) / (1 - sqrt(2)t + t^2)

Assunto: Re: [obm-l] integral

    Basta notar que
    int (tdt) / (1 - sqrt(2)t - t^2) = int {-t/[(t-t1)(t-t2)]}dt,
   onde
      t1= -[sqrt(2)+sqrt(6)]/2
    e
      t2= -[sqrt(2)-sqrt(6)]/2
  daí é só resolver através de frações parciais...
