Mean annual growth: This is a continuation . Forest managers study the mean annual growth M = M(A), defined as the yield at age A divided by A.

a. Use the formula for Y in to find a formula for M as a function of A.

b. Add the graph of M as a function of A to the graph of G.

c. The rotation age may be determined as the age of maximum mean annual growth. Determine the rotation age using the graph of M.

d. From your two graphs in part b, can you suggest a different way to find the rotation age?
