I’ve been trying to find an analytic solution to the following ODE. I haven’t been successful and have come to the conclusion that an analytic solution probably doesn’t exist. I am not totally sure though and would be appreciative if you guys gave it a look.(adsbygoogle = window.adsbygoogle || []).push({});

a & b are arbitrary constants...

[tex]

\ddot{f} + b tan(b t) \dot{f} - a^2 cos^2(b t) f = 0

[/tex]

Thanks in advance...
