Homework Help: IVP ODE checking specifics of solution

  1. Mar 9, 2013 #1
    1. The problem statement, all variables and given/known data
    I've got an IVP where,
    3xy+y2+(x2+xy)y'=0, y(1)=0

    3. The attempt at a solution
    I've solved to get,

    Is it correct to say,
    x=0 or y=0 or y=-2x,
    Since y= 0 is the only solution that fits y(1)=0, then
    y=0 [itex]\forall[/itex]x

    I didn't check your solution. But in any case, x=0 wouldn't be a solution. Otherwise, assuming your work is OK, yes.
