Comparison Tests

$⊳$ Direct comparison test (4:30) An introduction.
$⊳$ Worked example: direct comparison test. (4:54) Determine whether the series converges or diverges: $\sum_{n = 1}^{\infty} \frac{1}{2^{n} + n}$ .
* Practice: Direct comparison test. (4 problems)
$⊳$ Limit comparison test (6:52) Determine whether the series converges or diverges: $\sum_{n = 1}^{\infty} \frac{1}{2^{n} + 1}$ .
$⊳$ Worked example: limit comparison test. (7:18). What series should we use in the limit comparison test in order to determine whether $\sum_{n = 1}^{\infty} \frac{2^{n}}{3^{n} - 1}$ converges?
* Practice: Limit comparison test. (4 problems)
