Math 142A Fall 2017
Terminology and Theorems
Updated 10/3/17
Note: The following list is a minimal collection of the important terms and theorems for this course.
You simply must be familiar with them and how they are used: in the case of theorems, you should
be familiar with how they are proved. This basic knowledge is analogous to the vocabulary of a language: it
is impossible to speak the language without it.
