Averaged trig function with varying phase

  1. May 1, 2012 #1

    If you have say,


    where β is the phase and it fluctuates randomly (not just small fluctuations large ones) between 0 and 2∏

    the average value of cos(x+β) would still be 0 right?

    hey physicsjock! :smile:

    yes, provided that by "random" you mean that the distribution of ß is equally dense along the whole of [0,2π]
