2nd order

  1. Nov 1, 2009 #1
    [d]/[/dx](x*[dy]/[/dx]) = A*x

    is that equivalent to saying y'(x) + x*y''(x) = A*x

    then use the method of undetermined coefficients to solve it for y?

    Just need a start, not the answer. Thanks.

    You have an exact derivative on the left side as it stands. Just immediately take an antiderivative to get started.
