dealing with absolute functions that are limited always throws me off so lets consider this(adsbygoogle = window.adsbygoogle || []).push({});

f(x)=|x| for -∏ ≤ x < ∏

f(t)= f(t+2∏)

it's not too bad however finding the energy density is throwing me off a little..

the questions tend to be generally phrased as below:

Find the energy density of f(t).

-thanks guys and girls
