Professor Dave introduces power series, explaining their general form and how they can be represented as functions. He discusses the domain of these functions and provides examples to illustrate convergence and divergence. The ratio test is used to assess convergence, and a theorem is presented to summarize the possibilities for power series convergence. An example using X to the N over N factorial demonstrates infinite convergence.
