Have you ever had a teacher so good that you had to run out and tell all your friends? Introducing Dave’s online math course: Infinite Sequences and Series. Dave is recommended by his students because, as they say, he explains everything in great detail on every topic.

## Who This Course is For

- Students in college who want to learn more mathematics.
- Anyone interested in infinite sequences and series.
- Students who are enrolled in calculus 2 and want to improve their grade.
- Anyone interested in getting prepared for calculus 3.
- Anyone wanting to learn about sequences, series, various tests for convergence, power series, and the Taylor and Maclaurin series.

## Requirements

There is no required textbook, though you will need an up-to-date web browser, paper, and pen. A hand-held scientific calculator of your choice is required.

## Course Description

We start this interesting course off with a review of sequences. We discuss what sequences are, limits of sequences, limit laws for sequences, and the squeeze theorem for sequences. Next, we consider bounded monotonic sequences and then prove the monotone convergence theorem for sequences.

After this introduction to sequences, we begin a thorough investigation of infinite series. We discuss partial sums and convergence at length as well as geometric series and the harmonic series. Properties of convergent series and the divergence test are also detailed.

We then explore several convergence tests in detail, including the integral test, alternating series test, comparison tests, and the ratio and root tests. For each convergence test, we motivate why it is essential, how it works, and consider several examples.

After that, one of the main topics of calculus is explored: power series. We go into a great deal of attention on power series, including the Talyor and Maclaurin series. In the end, we examine approximation by Taylor polynomials, which is a generalization of linear approximation as studied in calculus 1.
