# Solution to real analysis

Turn in the homework on the due date. A random selection of the assigned homework will be graded. We will cover Chapters 1 through 5, and part of Chapter 7. Because I want you to learn from the feedback you get on your homework, as well as improve your writing skills, I will use a system of optional re-writes for the first few assignments, which will work as follows: Due at my office Shan by 1: Take-home due Fri Feb Special arrangements If you are a student with a disability registered by the Disabled Student Services DSS on UCB campus and if you require special arrangements during exams, you must provide the DSS document and make arrangements via email or office hours at least 10 days prior to each exam, explaining your circumstances and what special arrangements need to be done.

I expect all of us to be welcoming of the questions and explorations of others. The lowest homework assignment will be dropped. Sequences and series of numbers will then be discussed, and theorems presented to analyze their convergence properties.

It is helpful to remember that course grades are just intended to assess what you have learned.

Learn to read and write rigorous proofs, so that you can convincingly defend your reasoning. Your grade for a rewritten question will always go up or stay the same; it will never go down.

Though cooperation on homework assignments is encouraged, you are expected to write up all your solutions individually.

Rewrites will only be accepted for Homeworks 1 through 3. Part of the fun of this course is the struggle, as well as the joy of discovering a solution for yourself.

Late homeworks can be accepted with penalty by special permission.

There will be three exams: Hit a particularly tricky question? This course is a rigorous analysis of the real numbers, as well as an introduction to writing and communicating mathematics well. See also this guide.

If you choose to do a re-write, it is due at my office two weeks after the original due date of the assignment. Throughout the course, the use of rigorous mathematical proof will be emphasized. I do not encourage using these lectures as a substitute for class, however, since we will be doing slightly different things and interactions with me and other students will be critical for your learning.

Learn good mathematical writing skills and style, so that you can communicate your ideas effectively. Asking a study question in a snap - just take a pic. Please ask at least 24 hours in advance. Grade corrections The grades for exams will be changed only if there is a clear error on the part of the grader, such as adding up marks incorrectly.The modern solution to this natural issue is to introduce the idea of measurable functions, i.e.

a space of functions that is closed under limits and of the foundations of real analysis and of mathematics itself. The theory that emerged will be the subject of this course.

Here are a few additional points about this example. [RF] H. L. Royden, P. M. Fitzpatrick, Real Analysis (4th. 16 REAL ANALYSIS The above inequalities can be generalized to power means and weighted power means.
