Homework:
Homework is due on Gradescope on the day indicated below before 11:59 pm ET. Please upload your solutions by following the instructions in this video. Feel free to submit handwritten or work typeset in LaTeX (Overleaf is a great resource and tool for the latter). If you are skipping a problem, it is easier for the grader if you write "Skip" and upload that as your solution to the problem. You are more than welcome to work with others on the homework problems. However, the solutions should be written up on your own and reflect your understanding.

Course Catalogue Description:
This course introduces the basic concepts of real-variable theory. Topics include real numbers and cardinality of sets, sequences and series of real numbers, metric spaces, continuous functions, integration theory, sequences and series of functions, and polynomial approximation. Students may not take both Mathematics 35 and 63 for credit.
Learning Outcomes:
By the end of this course, you should be able to:
- Understand the real number system, metric spaces, continuity, differentiability, and Riemann integration;
- Solve mathematical problems: utilize abstraction and think creatively;
- Write clear mathematical proofs: recognize and construct mathematically rigorous arguments.
Additional Pages:
- Academic Honor Principle
- Expectations
- Student Accessibility Needs
- Mental Health
- Title IX
- Religious Observances
- Additional Support for your Learning
Additional Resources:
-
It is highly recommended to solve as many exercises from the textbook or other resources as you have time for. This will be more useful than rereading your class notes or textbook as it will often force you to go back to look at the material anyway. The only way to truly learn mathematics is through practice. Feel free to ask about your solutions.
-
There are many other textbooks and online materials that you can consult. If you have questions on whether a particular one might be useful, do not hesitate to reach out.
