Homework Help: Help with solving for y

  1. Sep 20, 2004 #1
    the initial diffferential question is
    y' = ty(4-y)/(1+t)

    i isolated the variables and integrated

    what i have is
    (1/4)ln4y - (1/4)ln(4-y) = t - ln(t+1) + c

    now i am supposed to express the general solution explicitly but i am don't know how to solve for y. any sort of suggestion would be greatly appreciated. thanks.

    Combine the logs on each side noting ln a - ln b = ln (a/b) and proceed from there! :-)
