Textbook Chapters

The chapter corresponding to this module is Introduction to Functions.

A PDF version of the textbook is also available here

You will be asked to log in with your CNetID before you can see the textbook.

Please note that the pre-recorded lectures cover largely the same material as the book. We recommend starting with the pre-recorded lectures, and then reading through the book (but do not feel bad if you find yourself skipping large portions of the textbook, if you feel they tread on material that you already understood when watching the lectures)

There are also two additional chapters that we encourage you to read once you’ve watched the videos and read the Introduction to Functions chapter:

Please note that these two chapters do not have any corresponding videos.
