CATALOG DESCRIPTION:
170B. Introduction to Numerical Analysis:
Approximation and Nonlinear Equations (4)
Rounding and discretization errors.
Calculation of roots of polynomials and nonlinear equations.
Interpolation. Approximation of functions.
Three lectures, one recitation. Knowledge of programming recommended.
Prerequisites: Math 170A.
COURSE INFORMATION:
Many of the advances of modern science have been made possible only through
the sophisticated use of computer modeling.
The mathematical foundation of the computer modeling techniques now used
in all areas of mathematics, engineering, and science is known as
numerical analysis.
The Math 170ABC series at UCSD provides an introduction to the exciting
field of numerical analysis, which is also sometimes referred to as
computational mathematics or scientific computing.
Professor Holst has a passion for this particular area of mathematics,
and much of his published research is in this area, and in particular in
the topics covered in 170B.
Math 170B deals primarily with the development and analysis of algorithms
(or, numerical methods) for solving systems of nonlinear equations, and
for doing approximation (of data, functions, or even solutions to
differential or integral equations).
GRADES, HOMEWORKS, EXAMS, AND IMPORTANT DATES:
Course information, such as homework assignments, due dates, and exam dates,
will be maintained on the class webpage.
Note that I sometimes make minor changes to the homework assignments as
the quarter progresses, based on how much I am able to cover in the lectures.
Therefore, CHECK THE WEBPAGE FREQUENTLY.
The course will be graded on the homework assignments, two midterm
examinations and a final examination, according to the following
guidelines:

Written and Computer HW (five homeworks): 

20% of grade 

Midterm #1 (In class week 4): 

20% of grade 

Midterm #2 (In class week 8): 

20% of grade 

Final Exam (Thu June 13, B402A AP&M) 

40% of grade 
Here are some other important dates:

First lecture: 

MON 4/1 

Last lecture: 

FRI 6/7 

Finals week: 

MONFRI, 6/106/14 

Holiday: 

MON 5/27 (Memorial Day  NO LECTURE) 
There will be five homework assignments throughout the quarter.
The first midterm will be based on homeworks 1 and 2.
The second midterm will be based on homeworks 3 and 4.
The final will be cummulative and based on homeworks 14,
as well as a small amount of new material from homework 5.
The following policies regarding homeworks and exams will be applied:
 I normally do not accept late homeworks so that I can post solutions
to the homeworks in a timely way for the class.
 The default plan is to have all HW assignments count towards the
final grade in the class.
UPDATE 06/11/2013: The CAPE response rate has now exceeded our target
of 70% (we hit 92.00%).
As promised, in return for your help with getting a good sample size
for the CAPES, I WILL now drop your single lowest homework score.
Your grade for the homework will then be the average of just your four
best scores.
Thanks again to all of you for helping get a good CAPE response;
it helps me improve as an instructor.
 In order to receive credit on a homework, you must at least attempt
the computer parts of the homework assignments (if there are any).
 There will be no makeup exams. If you miss a midterm with
an excused absence (i.e., illness with a note from a doctor), the
other midterm and the final exam will be weighted accordingly.
 You are not allowed (and will not need)
to use a calculator on midterms or finals.

You are allowed to bring a single 8x11 sheet of paper
containing
notes on both sides (formulas, whatever you find useful) to each midterm
and to the final. My view is that this allows you to focus on learning
how to do the problems and understanding the material, rather than
on memorizing formulas.

Hint for Midterms and Final:
The questions on all three exams should look very familiar.
I will make most of the problems on all three exams look very much like
the homework problems; in some cases, they will be exactly the same as some
of the homework problems, and in other cases, they will be minor
variations of homeworks.
(I will put at least one slightly more challenging problem on each
exam, which is not just a variation of a homework problem; this ensures
that everyone will have some challenge on the exam.)
LECTURES:
The lectures will follow the textbook quite closely.
Homework assignments will be a combination of theoretical and computer
problems; this will require some computer programming using MATLAB.
The TA will be able to assist you in accessing your computer accounts as
well as MATLAB.
