- Additional extra-credit problem:
Based on the error estimation given by the Integral Test,
if you can work out integrals of
*f*(where*f*is a decreasing function whose infinite integral converges), then you can estimate the infinite sum of*a*_{n}=*f*(*n*) using*m*terms and a couple of integrals with an error of at most ½∫_{m}^{m+1}*f*(*x*) d*x*, half of the integral of*f*from*m*to*m*+ 1. Using this, and if*p*> 1, what is the maximum possible error if you estimate the convergent*p*-series Σ^{∞}_{n=1}(1/*n*^{p}), the infinite series of 1/*n*^{p}starting with*n*= 1, using*m*terms? (Example 9.3.5 on page 510 of the textbook does this estimate in the case of*p*= 2 and*m*= 10, finding an error of at most ½∫_{10}^{11}(1/*x*^{2}) d*x*= ½(1/10 − 1/11) = 1/220 < 0.005.) When you have this expression, consider these limits:- As
*m*→ ∞ (so what happens to the error as you add more and more terms?) - As
*p*→ 1^{+}(so what happens to the error as you approach the divergent harmonic series?)

- Additional extra-credit problem:
Consider the ‘alternating
*p*-series’ Σ^{∞}_{n=1}(−1)^{n}/*n*^{p}, the infinite sum of (−1)^{n}/*n*^{p}.- For which values of
*p*does this converge? - If you approximate this series with
*m*terms, then what is the maximum possible absolute error (the maximum possible absolute value of the difference between the approximation and the true value) using the error estimate that goes with the Alternating Series Test? (Your answer will depend on both*p*and*m*.) - What is the limit of this expression as
*m*→ ∞? - What is the limit of this expression
as
*p*approaches the first value of*p*for which the alternating*p*-series diverges?

- Additional extra-credit problem:
Look at equation (10.2.4) on page 570,
and compare it to the equation that follows it
(which I'll call equation (5), although the textbook doesn't number it).
Treating d
*s*, d*x*, d*y*, and d*t*according to the ordinary rules of algebra for real numbers, and assuming d*t*≠ 0, simplify equation (4) as much as you can to get something like equation (5); pay especial attention to the algebraic rule √(*a*^{2}) = |*a*| (not simply*a*). Treating equation (5) as correct (as motivated by Figure 6.27 on page 370 and noting that d*s*is supposed to represent a length), what should equation (4) be so that it will simplify to equation (5) exactly? Can you think of a situation in which integrating this modified version of equation (4) would give the correct value for the arclength of a parametrized curve while integrating the textbook's version of equation (4) would give a wrong value? (This would have to be a situation that violates some of the fine print in the definition on page 567 of the textbook, because there is nothing wrong with that definition as far as it goes.)
