For an equation of the form:
(in this case and )
For this case:
and hence
So to the guts of the problem (remembering the constant of integration at this stage):
Checking:
To determine C you'll need a known point
Use a suitable trial function to find the particular solution of
From the equation,
Now I don't understand the last bit where you have to pick the two parts which correspond to 0 and 3. Could someone explain it for me?
