Small angle approx

Small angle approx

Just added some examples of this

 

- wasn't really a topic when I studied A-level - or at least until mechanics 3 and the discussion of pendulums! (for clarity, the simple harmonic motion of a pendulum is a consequence of using $x\approx \sin(x)$ when modelling the motion of a pendulum! Anyhow the basic examples of small angle approximations can be found here ; small angle approximations. More sophisticated examples to follow.
