(a) For which real numbers x is ((x) defined? (Or: for what values of x does this sum converge?)
(b) Use the sum of the first 10 terms to estimate the sum of the series (2) = 1/n², which is the
p-series with p = 2 (you will need a calculator). How accurate is your estimate? (ie. What is the
upper bound on the remainder R.)
(c) It turns out that ((2)=. Pretend that you do not know the numerical value of л. Using the
formula
Sn+
++ for f(x) dx < s < S₁ +
+ f(x)dx
what bounds do you get on the numerical value of 7²/6 from using the first 10 terms in the series?
How close do you get to the numerical value of n? (Again you will need a calculator.)
