Series | The Root Test: Theory and 2 Examples

The video tutorial covers the root test, a method for determining the convergence or divergence of series, particularly when terms are raised to a power. It explains the conditions under which the root test is applicable, how to calculate it, and how to interpret the results. Two examples are provided: one where the series converges and another where it diverges. The tutorial also discusses alternative tests to use when the root test is inconclusive.
