Series Solution

  1. Oct 17, 2006 #1
    Hi everyone,
    Can anyone help me find the solution of this equation using series?

    xy"+(sinx)y'+2xy=3x^2
    y(0)=y'(0)=1

    Thanks in advance

    Sure, what have you got so far?

    I know that 0 is an ordinary point and therefore I can write the solution in form of series. But I don't know what to do with sin x.

    If you assume a series solution you have to compare coefficients later on, so it would help if sin x is written as a series.
