## Requirements for the Majors

### Mathematics

The mathematics curriculum emphasizes solving problems by rigorous methods that use both calculation and structure. Starting from the first year, students learn to write mathematical arguments. Students discuss the subject intensely with one another outside the classroom.

#### Requirements for the Mathematics Major

- Mathematics 111 or the equivalent, 112, 113, 201, 202, 321, and 332.
- Four additional units in mathematics courses numbered higher than 300 (excluding Mathematics 470).
- Physics 101 and 102 or the equivalent.
- Mathematics 470.

#### Requirements for the Mathematics Major with Concentration in Computer Science

- Mathematics 111 or the equivalent, 112, 113, 201, and 202.
- Mathematics 121 or the equivalent, and 221.
- Mathematics 382, 387, and 389.
- Three additional units in mathematics courses numbered higher than 300.
- Mathematics 470.

The mathematics junior qualifying exam would include an optional component in computer science.

#### Requirements for the Mathematics Major with Concentration in Statistics

- Mathematics 111 or the equivalent, 112, 113, 201, and 202.
- One data analysis course, either Mathematics 141 or 241.
- Mathematics 321, 391, and 392.
- Two additional units in mathematics courses numbered higher than 300.
- Mathematics 470.

Strongly recommended: Mathematics 121 and 221, and courses in fields of application such as biology, psychology, sociology, or economics.

### Mathematics-Economics

The mathematics–economics major gives the student an opportunity to acquire a firm foundation in both fields during the normal four-year college program without sacrificing electives. Modern economic analysis relies heavily on the application of mathematical methods. The joint major is particularly useful for students who intend to do graduate work in economics. Early consultation with members of both departments is important for students considering this major.

#### Requirements for the Mathematics-Economics Major

- Eight units of mathematics to include Mathematics 111, 112, 113, 141, 201, 202, and two other mathematics courses chosen from courses numbered higher than 300. Recommended: selections from Mathematics 321, 322, 332, 382, 391, and 392. Students should also consider taking a 200-level statistics course. At the discretion of the Department of Mathematics, Mathematics 111 may be waived for students entering with sufficient background in calculus. Students with adequate background in statistics may substitute a 200-level statistics course or an upper-division mathematics course for Mathematics 141.
- Six units of economics, including Economics 201, 312, 313, and 314, and two units from among Economics 315–469, excluding Economics 402.
- Two units in one department in the Division of History and Social Sciences, excluding Economics.
- The junior qualifying examination is taken in both departments.
- Mathematics–Economics 470 (thesis). The thesis is usually jointly supervised.

### Mathematics-Physics

A program intended to serve the needs of students whose major interests lie in the rich area between applied mathematics and theoretical physics. The student planning to major in mathematics–physics should consult with the head of the committee as early as possible to determine if they are qualified and, if so, to plan a program. Both departments must approve the application.

#### Requirements for the Mathematics-Physics Major

- Mathematics 111 or the equivalent, 112, 113, 201, 202, 322, and two other mathematics courses numbered higher than 310, including at least one of 311 or 321.
- Physics 101, 102, 201, 202, 311, 321, 322, 342.
- The junior qualifying examination is taken in both departments.
- The thesis (Mathematics–Physics 470) must clearly bridge the two fields.

Strongly recommended but not required:

- Two from Physics 323, 351, 362, 411, 442.

Recommended but not required:

- Mathematics 332, 411.
- Working knowledge of a foreign language: Russian, German, or French.
