Math 51 Autumn 2017


Office hours and other resources for help



Math 51 lectures will
primarily be devoted to
developing the underlying concepts and theory, although some examples
will also be given. Discussion sections will primarily be devoted to
examples and review of the theory. Assigned homework problems will NOT
be worked out in sections, although at times some similar "daily
discussion problems" will be worked out.

College mathematics
courses are much harder than high school courses, and the expectations
of the professors are much higher. A rule of thumb is that you should
spend two to three hours working outside of class for each inclass
hour. Since Math 51 meets five hours each week, this means you should
expect to spend 1015 hours outside of class working on the course
material, studying the textbooks, the notes, and working on problems,
perhaps even more than those assigned.

In order to be certain of
doing well on
examinations, it is important that you truly understand the material,
and not just memorize certain mechanical techniques. Over 900 students
at Stanford complete Math 51 each year. Several hundred of these
students go on to study advanced topics in mathematics, statistics,
physics, computer science, engineering, economics, and other fields.
The Math 50 series courses are designed to make that possible, but a
student who just gets by in a basic course (in any subject) by
memorizing as needed to get through exams, will probably not be
successful at more advanced levels down the road.

Read and take notes on the
chapter associated
to the exercises before completing them. Reading math takes longer than
reading fiction. Be prepared to spend some time studying each section,
with pencil and paper nearby to take notes, write down questions, or
fill in gaps in the steps given in the book.

Write up neat solutions to
homework, not a
collection of scrap work that resulted in the right answer. Be critical
of your own solutions: Is each step clearly explained? Is the logic
sound? Most homework problems will be calculations, but students will
also be asked to give some proofs. A proof must be a logical,
sequential argument, with no holes, gaps, or errors. To write a
satisfactory proof, you must use exact definitions.

It is a very good idea to
learn the
definitions of terms as they come up in the course. In mathematics,
probably more than in any other subject, new ideas are built on and
depend on previous ideas. If you fall behind in understanding
definitions it can be almost impossible to learn and understand the
ideas later on in the course. Don't let that happen! Try to spend some
time comprehending the new definitions that come up in each section of
the textbook. Homework will also help with this.

Office hours of both the
TAs and Professors
are an opportunity to discuss difficulties you are having with concepts
and homework problems. You will get much more out of coming to office
hours if you have spent time beforehand trying to do the problems. All
students may go to the office hours of any of the Professors or TAs.
These are set at a wide variety of days and times.

We do allow and encourage
students to work
with each other, and the course staff, in the preliminary stages of
completing homework assignments. However, each student must then write
up in his or her own words the actual solutions submitted for grading.
To simply copy solutions from someone else is an Honor Code violation.
Stanford's Honor
Code and Fundamental
Standard are taken very seriously. By Math Department policy,
any student found to be in violation of the Honor Code on any
assignment or exam in this course will receive a final course letter
grade of NP.

In addition to the office hours of Professors
and TAs, there is a
SUMO help center
for students in the Math 50 series courses, held
Monday and Wednesday evenings 6:0010:00 PM in Room 381T of
Math building 380. You can get help with homework problems
or with
reviewing material covered in class. Other free resources are available
at the Tutoring Center
sponsored by the
Center for Teaching and Learning.
