Description

The course on Integration and Infinite Series will treat, among others, methods of differentiation, methods of integration, series and their convergence, and relations between these concepts. The prerequisites required for this course are covered in Math 31A.

The course will have weekly classes on

The book we will be following is Single Variable Calculus (2nd edition) by Jonathan D. Rogawski. We will be covering material in Chapters 7, 8, 9, and 11. You may find all the information you will need on the Syllabus.

Resources

There are many resources available for a student at UCLA, I encourage you to use them and make the most out of them. Here are some materials specific to this course:

I also encourage you to form study groups with your classmates. However, please keep in mind that you will only learn how to do the exercises if you try them on your own: without trying, looking up the solutions or copying others' work is absolutely useless.

Grading Schemes

You can compute your final grade using the calculator below. Please input the average of your homework assignments (out of 100), the average of your discussion assignments (out of 100), the score of your first midterm (out of 100), the score of your second midterm (out of 100), and the score of your final (out of 100). Then, click "Compute grading schemes" to see the three grading schemes (out of 100).
