### Textbook:

A bound set of lecturer-prepared notes (2017 version) will be available for purchase from the UT
Copy Center, Union location, UNB
2.214. A recommended supplemental text is E. Kreyszig, Introductory Functional Analysis with
Applications, Wiley, 1978.
### Meeting:

MWF 11:00-12:00 p.m.,
RLM 11.176.

### Class Web Sites:

We will use the University's Canvas web site. Please check
that your scores are recorded correctly in Canvas. You can access Canvas from
my.utexas.edu.
### Homework, Exams, and Grades:

Homework will be assigned regularly. Students are encouraged to work in groups; however, each
student must write up his or her own work. Two mid-term exams will be given in approximately weeks
six and eleven (the weeks of Oct. 2 and Nov. 6). The final exam will be comprehensive and given
Tuesday, December 19, 9:00-12:00 noon. Grades will be recorded in the University Canvas system, so
students can check their scores directly. The final grade will use the plus/minus system and be
based on the homework and the three exams, with somewhat greater emphasis on the final exam.
### Course Description:

This is the first semester of a course on methods of applied mathematics. It is open to
mathematics, science, engineering, and finance students. It is suitable to prepare graduate
students for the Applied Mathematics Preliminary Exam in mathematics and the Area A Preliminary Exam
in CSEM. The first semester is an introduction to functional analysis.
