• To help you become informed about the range of opportunities available to you as math majors, both over the next year and after you graduate.

You can find a link to the syllabus here.

## Assignments

#### Week 1: Due Thursday, January 31

• Complete a practice Calc 1 section of the comps exam.
• Use $\LaTeX$ to typeset your answers for the Calc 1 exam; you should include a \maketitle command that gives a title and your name and the date.
• If you haven’t already, fill out this short survey on how comfortable you feel with each topic on the comps study guide. Use 1 for topics you don’t remember at all, and 5 for topics you feel completely comfortable with. Please complete this by Saturday.

#### Week 2: Due Thursday, February 7

• Study for the Calc 1 comps exam.
• Read the solutions to the practice Calc 1 section.
• Submit an abstract you have written for the Krebs and Wright paper we discussed in class.
• Write it in $\LaTeX$ and use the \begin{abstract} \end{abstract} environment.

#### Week 3: Due Thursday, February 14

• Complete a practice Calc 2 section of the comps exam. (You don’t need to type it up this time; feel free to handwrite it, but turn it in).
• Sign up for a slot to talk about one comps review topic at this link. Note: Due to a technical screwup on my part, there is one multi topic and one calc 2 topic listed at the end.
• If you are giving a talk next week: Send me a copy of your notes for the talk by Monday night. That way I can give you feedback and make sure you’re leading everyone else in the right direction.
• Choose a paper to summarize for your first paper of the course (see below). Print out and bring to class a brief abstract for the paper, written in $\LaTeX$.
• Review notes on giving a talk.

#### Week 4: Due Thursday February 21

• Read the solutions to the practice Calc 2 section.
• Bring four printed copies of your resume into class on Thursday.

#### Week 5: Due Thursday February 28

• Complete a practice multi section of the comps exam. (You don’t need to type it up this time; feel free to handwrite it, but turn it in).
• If you are giving a talk next week: Send me a copy of your notes for the talk by Monday night. That way I can give you feedback and make sure you’re leading everyone else in the right direction.
• Turn in a printed out hard-copy rough draft of your summary paper assignment.

#### Week 7: Due Thursday March 21

• Complete a practice linear section of the comps exam. (You don’t need to type it up this time; feel free to handwrite it, but turn it in).
• If you are giving a talk next week: Send me a copy of your notes for the talk by Monday night. That way I can give you feedback and make sure you’re leading everyone else in the right direction.
• Turn in a printed out hard-copy final draft of your summary paper assignment. Some tips:
• I encourage everyone to use BibTeX for citations, but it can be a little tricky if you’ve never done it, and it’s not a requirement. This tutorial should explain how; with the note that you can use Google Scholar to get you your .bib file and shouldn’t need to format it yourself.
• $\LaTeX$ doesn’t automatically create smart quotes for you, and thus you shouldn’t type "words" if you want quotation marks. Many editors will fix this for you, but if yours doesn’t, it is much better to type words'' instead. (The backtick mark is probably under the tilde in the upper-left of your keyboard, right below the escape key).
• If you’re using a function with a long name in math mode, make sure you mark it as a function.
• If $\LaTeX$ already recognizes your function you can just type it with a backslash: so \log instead of log or \gcd instead of gcd.
• If $\LaTeX$ doesn’t recognize your function, you need to tell it. You can either type something like \operatorname{area} every time instead of just area, or you can add \DeclareMathOperator{\area}{area} once to the preamble. (Both of these options will only work if you are using the package amsmath).
• If you’re typesetting an integral, it can be helpful to type \,dx instead of dx

#### Week 8: Due Thursday March 28

• Read the solutions to the practice linear section.
• Study for the linear comps exam.
• Submit an abstract for the Theorem paper.

#### Week 9: Due Thursday April 4

• Complete a practice Discrete section of the comps exam. (You don’t need to type it up this time; feel free to handwrite it, but turn it in).
• If you are giving a talk next week: Send me a copy of your notes for the talk by Monday night. That way I can give you feedback and make sure you’re leading everyone else in the right direction.
• Turn in a printed out hard-copy rough draft of your theorem paper assignment.

#### Week 10: Due Thursday April 11

• Read the solutions to the practice discrete section.
• Study for the discrete comps exam.
• Bring three printed copies of your draft paper in to class.

## Mathematical Communication

You may find the introduction to LaTeX I wrote elsewhere on this site helpful.

### Summary Paper

• The goal of this assignment is to learn to communicate about mathematical ideas to an audience unfamiliar with the ideas you’re discussing. You should think of the audience as being your fellow math majors: mathematically skilled but unfamiliar with the specific topic and field you are working in.

You should communicate the basic ideas, goals, and methods of the paper, but not get bogged down in the weeds of detailed calculations, technical arguments, or details of proofs.

• Choose a paper to summarize. The paper should probably be in the 4-10 page range.
• Rubric for the summary paper is here.
• You need to tell me the paper you have chosen and write an abstract for your summary paper by Thursday, February 14.
• Rough draft is due Thursday, February 28.
• Final draft is due Thursday, March 21.

### Theorem Paper

• The goal of this assignment is to learn to communicate about mathematical ideas to an audience unfamiliar with the ideas you’re discussing. You should think of the audience as being your fellow math majors: mathematically skilled but unfamiliar with the specific topic and field you are working in.

• Choose a theorem, result, or technique from a 300- or 400-level math class you have taken or are taking. You will write a paper of approximately three pages in which you clearly state the result, explain how the result was obtained, and tell your reader why this result is relevant and important.
• Mathematical results from courses in other departments may be approved on a case-by-case basis, but please consult with me to confirm.
• Rubric for the theorem paper is here.
• You need to tell me the paper you have chosen and write an abstract for your summary paper by Thursday, March 28.
• Rough draft is due Thursday, February April 4.
• Final draft is due Thursday, April 18.

### Final Presentation

• The goal of this assignment is to practice communicating mathematical ideas to an audience via a verbal/slideshow presentation. The audience will be your fellow math majors. Assume they are mathematically skilled, but unfamiliar with the specific topic you are discussing.
• Choose a theorem, result, or technique from a 300- or 400-level math class you have taken or are taking. You will give a ten-minute slideshow presentation in class in which you will explain the result, the basic ideas behind it, and the reason it is important and relevant.
• Mathematical results from courses in other departments may be approved on a case-by-case basis, but please consult with m to confirm.)
• Slides from my in-class Beamer presentation are here. You can also download the TeX source code or the plain text source code.
• You can find the rubric for the talk here

## Comps Part 1

The math comprehensive exam will consist of five sections given on five separate days, spread throughout the semester. Each section will cover one of the five fundamental courses. Dates for these exams are:

 Thursday, February 7: Calculus 1 Thursday, February 21: Calculus 2 Thursday, March 7: Multivariable Calculus Thursday, March 28: Linear Algebra Thursday, April 11: Discrete Mathematics

There is a study guide available here that tells you what topics we think are most important. You can also download a complete (if somewhat dated) list of topics for each course:

We have a number of practice exams from previous years available.

## Future Opportunities

I encourage everyone to look for a job/internship/research opportunity this summer. This will improve your resume, and also give you a better idea what sorts of things you might want to do after you graduate. Many of these opportunities will pay you reasonably well.

Occidental has an undergraduate research program to sponsor you doing research with a professor. You would need to find a professor to mentor you; the program comes with a \$4500 stipend and subsidized (but not free) summer housing. The deadline is February 9.

#### Other Research Opportunities.

The NSF REU program funds experiences where a group of undergraduates from different institutions gather and do research on a math topic for ten weeks over the summer; typically the students also receive a stipend of several thousand dollars.

A list of programs running this summer is available here. Deadlines are typically in February and March. (Most NSF programs are only available to US permanent residents).

There are also a number of summer programs listed at mathprograms.org. You can look around without making an account; the list of undergraduate programs seems to be here.

#### Internships

The AMS has an info page rounding up several summer internship opportunities.

The MAA also has a page of internship opportunities. It also has a roundup pages on careers here.

SIAM has a page on internships and careers.

I’ll try to add more resources as I find them.
