A List of Concepts, Theorems and Methods Mathematics 113/114, Section D2 Below are listed most of the concepts, important theorems and methods covered in the Math 113/114 class. You should be familiar with things on this list. In the case of theorems, make sure you know the content of all of them, and know when and how to apply them. The methods listed should be familiar: know what type of situations each is useful in (so that when presented with a question, you can quickly decide what to do.) The material in the appendices should mostly be review. You should be comfortable enough with the material there to understand everything we covered from Chapters I-V. In addition, I recommend perusal of the textbook reference pages. Be familiar with trigonometric functions, their elementary properties and identities, their values at the most important angles. The derivatives and antiderivatives of the most common functions (trigonometric, exponential, inverse trigonometric, logarithmic) should be readily at hand. Finally, it is good to have an example in mind for the concepts and definitions you learn. It makes learning a lot easier, and having a few functions in mind can be a big help with multiple choice questions.
