Hello I was recently working on a problem where I had to solve the differential equation in the title ( where y is a function of t), I found an exact series solution through peturbation theory in which a pattern emerged between successive orders.(adsbygoogle = window.adsbygoogle || []).push({});

However, the series solution is not very useful for computation and I would like to ask if anyone knew a special function which solved this equation?
