Use the Laplace transform to solve the given initial value problem.(adsbygoogle = window.adsbygoogle || []).push({});

y"+[w^(2)]y=cos2t, w^(2) does not equal 4; y(0)=1, y'(0)=0

I tried doing the problem, and I got up to Y(s)=[(s^(3)+5s]/[s^(2)+w^(2)],

which hopefully is correct. Now I'm having trouble using the Laplace

transforms to finish solving the problem.

Thanks for your help!
