I have the ODE:(adsbygoogle = window.adsbygoogle || []).push({});

[tex]y^{(4)}+2y''+y = 3 + cos(2x)[/tex]

I believe I can use undetermined coefficients for the particular, but I'm not sure and it isn't working well for me so far, and the homogeneous looks nasty and I'm not sure what to attempt with.

Thanks!
