(a) Compute $s_3$ of $\sum_{n=1}^{\infty} \frac{9}{9n^8}$ (b) Estimate the error in using $s_3$ as an approximation of the sum of the series. (i.e. use $\int_3^{\infty} f(x)dx \ge r_3$) (c) Use $n=3$ and $s_n + \int_{n+1}^{\infty} f(x)dx \le s \le s_n + \int_n^{\infty} f(x)dx$ to find a better estimate of the sum. $\Box \le s \le \Box$
