The AM – GM inequality states that for positive numbers ak, (1/n)(a1 + a2 + . . . + an) is greater than or equal to (a1a2an)1/n, with equality when and only when all of the terms ak are equal. If some of the ak are known values, not necessarily all equal, and the rest are allowed to vary, we will look at how close (in terms of difference, and in terms of ratio) the two means can be, and determine exactly when these extreme states occur. Only methods of basic calculus will be needed.

Refreshments will be served.
