# Sequences and Series

## by The Ohio State University

This course material is only available in the iTunes U app on iPhone or iPad.

#### Course Description

Sequences and Series will challenge us to think very carefully about "infinity." What does it mean to add up an unending list of numbers? How can an infinite task result in a finite answer? These questions lead us to some very deep concepts, but also to some powerful computational tools which are used not only in math but in many quantitative disciplines.

This course is a first and friendly introduction to sequences, infinite series, convergence tests, and Taylor series. It is suitable for someone who has seen just a bit of calculus before.

#### Customer Reviews

##### Simply great for the already math inclined

This course is terrific for those already mathematically inclined. The professor has a fun attitude, the visuals are extremely helpful (and sometimes sophisticated), and the content can, for the most part, be followed easily and logically from one step to the next. As someone who has taken advanced mathematics courses which brush up against the subject of sequences, this course has greatly filled in some foundational gaps.

Thanks so much to the author/presenter.
