I got a physics tie and was wondering what the following formulae meant

the first one is the parallel axis theorem.

This is what I found on wikipedia.

P-series

A generalization of the harmonic series is the p-series (or hyperharmonic series), defined as:



for any positive real number p. When p = 1, the p-series is the harmonic series, which diverges. Either the integral test or the Cauchy condensation test shows that the p-series converges for all p > 1 (in which case it is called the over-harmonic series) and diverges for all p ≤ 1. If p > 1 then the sum of the p-series is ζ(p), i.e., the Riemann zeta function evaluated at p.

Rishabh95's right. Here's more info:

In all honesty the equation has more to do with mathematics than physics, although I guess it can crop up on occasion.
