(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

By using the method of undetermined coefficients,find the particular solution of

y''+y'+y=(sin x)^2

2. Relevant equations

i know how to determine the particular solution IF it is sin x.

Ex: sin x ====> Asin x + B cos x (particular)

but i wonder how to determine the (sin x)^2

3. The attempt at a solution
