Hi,I need to show that the following equation is not solvable:Any idea? Thank youQuote:

$\displaystyle \ddot{\theta}(t)+a\dot{\theta}(t)+b\sin\theta(t)+\ sin\left(ct\right)\sin\theta(t)=0 $

Is $\displaystyle \displaystyle \begin{align*} \theta \end{align*}$ a function of $\displaystyle \displaystyle \begin{align*} t \end{align*}$?

$\displaystyle \theta $ is a function of t.My idea was to use Laplace transorm on the equation, but I am not able to.
