## Homework Statement

I want to calculate g from the formula for the period of a pendulum. The trouble is the uncertainties.

## Homework Equations

[tex]g = \left(\frac{2 \pi}{T_0}\right)^2 L[/tex]

[tex]T_0 = \frac{T(\phi_{max})}{1 + \frac{1}{16}\phi_{max}^2}[/tex]

[tex]T(\phi_{max}) = 1.99433 \pm 0.00005 \ \mathrm{s}[/tex]

[tex]\phi_{max} = 0.010 \pm 0.005[/tex] (radians)

[tex]L = 0.98967 \pm 0.00002[/tex]

## The Attempt at a Solution

I really have no idea. Do I use error propagation?
