SUMMARY

The formula for the period of a simple pendulum, represented as T0 = 2π√(g/L), is dimensionally incorrect according to forum participants. The discussion highlights that the power series used aligns with this erroneous formula, leading to confusion. Participants agree that the fraction is inverted, and reputable sources like Wikipedia and Hyperphysics support this correction. This indicates a need for reevaluation of the formula in educational materials.

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.
