Course Information:
This course is an introduction to the rigorous foundations of single-variable calculus - real number system; limits; convergence of sequences and series; continuity, differentiability, and integrability of functions.
The Course Information Handout has extensive description of the course - topics, textbook, student evaluation policy, as well as other relevant information. Read it carefully!
What is this course really about? Required reading.
The official course syllabi: MATH 400 (refer for topics only).
The end-of-semester letter for students: What Next?
Advice for students:
Excellent advice by Francis Su on good mathematical writing.
Why do we have to learn proofs?
Understanding Mathematics - a study guide
On a more abstract note, here is a discussion of Language and Grammar of Mathematics - which is what you are learning in a course like this.
Excellent advice for math majors, especially those planning to go on to graduate school, by Terry Tao, 2006 Fields medallist. Required reading.
Read this book on a variety of experiences in the journey to learn mathematics:
