Classical Mistake in K&K mechanics?

  1. Feb 24, 2015 #1
    In the section on approximation methods, the formula for the period of a simple pendulum of length ##L## is given by:
    $$T_0 = 2\pi \sqrt{\frac{g}{L}}$$
    I am no expert on simple harmonic motion, but it is clear that the equation is dimensionally incorrect.
    The problem is, the power series used is in accordance with the (possibly) faulty expression I wrote above. Thoughts?

    Yes I would say that is a mistake - the fraction is the wrong way up. I had a feeling it was, but I checked and Wikipedia agrees. Their equation is given with a citation, but if you prefer, I have found Hyperphysics a reliable source of help with physics problems, and it shares my view.
