I've been trying to derive the period of a physical pendulum, and I ended up with a differential equation that boils down to this:(adsbygoogle = window.adsbygoogle || []).push({});

[tex]

\frac{d^2 \theta}{dt^2} = C \sin{\theta}

[/tex]

where C is some constant.

With no experience in differential equations, I have no idea how to solve this. I can't find anything about how to solve this type of differential equation, so if someone could point me in the right direction, that would be helpful.

Thanks!
