Homework Help: ODEs- Wronskian

  1. Mar 25, 2010 #1
    1. The problem statement, all variables and given/known data
    the wronskian of f, g and h is 6x
    W(f,g,h)=6x
    f(x)=1
    g(x)=x
    h(0)=0
    h'(0)=0

    find h(x).

    2. Relevant equations



    3. The attempt at a solution
    I just need someone to solve it and compare it with my answer.

    from the Wronskian I get
    h''=6x
    I use the method of undetermined coefficients and find that:

    h(x)=t3

    Is this correct ?
    I went over this a few times and I didn't find any mistake, but I'm not sure about this.
    Would appreciate if someone could also solve it.

    yes that is correct, just you have h(x) and not h(t) so h=x3

    yea right x^3

    Thanks a lot...
