I bought a stock two years ago for 100. Now it is worth 121. What is the average annual percent increase?
100*(P^2) = 121; the P^2 is because of the two years.
P^2= 121/100 = 1.21
Take square roots of both sides
P = 1.1, or a 10% increase.

The volume of water accumulated in the reservoir of a hydroplant is a function of the water level. In general, the function that relates the volume V to the water level h is
V(h) = a h^b if h <=h0
V(h) = b h^c if h > h0
The problem is to determine the parameters a, b , c and d so that we minimize the sum of the sqare of the differences between the given and the estimatesd values of V.
