Hoped everything is fine. I want to integrate the following expression under the different conditions of discriments Delta. 

int(1/(a[3]*(u(eta)^3+d[2]*u(eta)^2+d[1]*u(eta)+d[0])), eta);

when Delta = 0;Delta > 0 and Delta < 0.

where discriments Delta = -27*(2*(d[2])^3/27+d[0]-d[1]*d[2]/3)^2-4*(d[1]-(d[2])^2/3)^3;

I am waiting your positive respone.
