**MathMate**, Thursday, August 26, 2010 at 8:29amIf we look at the cosine function which can be written as

cos((t/52)2π), we conclude the cycles are over periods of 52 weeks, meaning yearly cycles.

The first two terms represent a straight line with a y-intercept of 8, and constantly increasing at the rate of (1/52).

Can you deduce the answer from the above information?
