we know when theta is considered small enough, sin(theta) is approximately equal to theta. Ok, the question is what happens to theta dot(the time derivative of theta)?

If [itex]\theta[/itex] is small all the time, the timederivative of [itex]sin(\theta)[/itex] is approximately the timederivative of [itex]\theta[/itex].
