Let a and b be positive numbers with a > b . Let a 1 be their arithmetic mean and b 1 their geometric mean: a 1 = a + b 2 b 1 = a b Repeat this process so that, in general, a n + 1 = a n + b n 2 b n + 1 = a n b n (a) Use mathematical induction to show that a n > a n +1 > b n +1 > b n (b) Deduce that both { a n } and { b n } are convergent. (c) Show that lim n →∞ a n = lim n→∞ b n . Gauss called the common value of these limits the arithmetic-geometric mean of the numbers a and b .

Solution Summary: The author explains that if a and b are positive numbers, then a_n+1>sqrt
Use the method of washers to find the volume of the solid that is obtained
when the region between the graphs f(x) = √√2 and g(x) = secx over the
interval ≤x≤ is rotated about the x-axis.
