Preliminary Course Outline

Homework and notes will appear here.

Note on mindmaps: Mind maps are graphical representations of information. I will also post basic mindmaps of lectures created using FreeMind, both in the native .mm format and exported as pdf. I encourage you to use these to create more prsonaliszed versions as a study strategy and a review tool. If you have questions about mind maps let me know.

Grade Policy

Lowest 2 homework scores will be dropped. Homework 20 %, Midterm 30%, Final 50%.

Course Objectives

The goal of this course is to understand the theory behind single variable calculus. This includes understanding real numbers, their sequences and series, limits, continuous functions, derivatives and integrals. Honors math majors and students who intend to do graduate work in mathematics should take 171.

Homework

Homework is due weekly in Wednesday lecture, as detailed in the course outline. Late homework will not be accepted, absent a bona fide emergency; however the lowest 2 homework scores will be dropped. You are encouraged to discuss homework with me, your CA, and your classmates, however the final write-up should be entirely your own. We abide by the Honor Code.

Extra Help

Dot not hesitate to come to my office during office hours or by appointment to discuss a homework problem or any aspect of the course. You also may want to consider talking to Stanford University Mathematical Association(SUMO).

Important dates

  • Add/Drop Deadline: October 12
  • Midterm: October 26
  • Final: 12/14/2012 HERRINT195 8:30 AM to 11:30 AM
  • Textbook

    We will follow Elementary Analysis: The Theory of Calculus, by Kenneth A. Ross.

    Similar material is covered in the first part of Undergraduate Analysis, by Serge Lang, which you may consult if you want to see a different exposition.

    Prerequisites

    This is a proof based course, so plan accordingly. The book The Nuts And Bolts of Proofs, by Antonella Cupillari is often recommended for transitioning into proof based material. Formal prerequisite for the course is Math 51.

    Vi Hart gives 9.999... reasons why 0.999...=1, and then why they are all wrong (note the upload date).

    She also explains the difficult relation Pythagoras had with irrationality and beans, a subject we touched upon in Lecture 2.

    Oct 17: The midterm location is confirmed - 380-380W. This is in the basement of the math building. Midterm time is 10-11:30 and 4-5:30 on Friday Oct 26.

    First part of homework 4 is up. Homework 4 is due in about 2 weeks- Wednesday, October 31. However if you want to get a leg up and practice the latest material before the midterm you can start on it.

    Lecture 11 notes up.

    Questions and Concerns for week 3 are up.

    Oct 12: The supplementary notes on proof creation and proof writing are posted. I strongly encourage you to take a look and read the parts that seem relevant for you.

    Midterm is preliminarily scheduled for Friday 10-11:30 with alternate time of 4-5:30 that evening. If you can not make both of those times let me know by Monday end of lecture. Midterm location is to be determined.

    Lecture 8 notes updated, Lecture 9 notes up.

    Oct 8: Courtsework site is live, and grades for HW1 posted. Survey results are here and also here: The first two bar charts are difficulty/speed of lectures and length/difficulty of homework. Most people answered "3-Just about right". The other three charts are overall impression of the course, understanding of material and important vs. unimportant concepts in the course.
