- ##ml^2\ddot \phi + mRl\varphi \dot \phi\sin(\phi - \varphi t) = 0##

For (d),

I am confused how ##a(t)## oscillates harmonically. The EOM is ##ml^2\ddot \phi + mRl\varphi \dot \phi\sin(\phi - \varphi t) = 0##

Then using ##\phi - \varphi t = a(t)##

##l\ddot \phi + R\phi \varphi a(t) = 0##

Where I used the small angle approximation after substituting in ##a(t)##

Does anybody please know where to go from here to find ##\omega##?

Thanks!
