Homework Statement


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).

Homework Equations





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...
