Use the ratio test to determine the convergence or divergence of the following series.

- \[\sum_{n=1}^\infty \frac{n^3 3^{n+1}}{4^n}\]
- \[\sum_{n=1}^\infty \frac{n^{10}}{10^n}\]
- \[\sum_{n=1}^\infty \frac{n^n}{n!}\]

Complete the following questions before our next class.

(From the Haese book)

Exercise B.1 questions 3 and 5

(Read Section J, then complete )

Exercise J.1 questions 1bdf, 2acdf, 3

Exercise J.2 questions 1, 2, 3

Pay particular attention to questions 1 and 2 in J.2, which makes use of two (often useful) algebraic methods for showing that a sequence is monotonically increasing/decreasing: a sequence is decreasing if either \(u_{n+1}-u_n <0\), or \(\frac{u_{n+1}}{u_n} <1\) for all \(n\), and with inequalities reversed either method establishes that the sequence is increasing.
