### Required for the interdisciplinary mathematics-economics major

- The mathematics component of the major is:
- MATH 140, 150, 160, 207, 300, and 310
- Either MATH 435 or 445 and 6 units in a mathematics course numbered 400 or above, with 435, 440, 445, or 560 recommended

- The economics component of the major is:
- ECON 100 or 120
- ECON 300, 320, and 380
- Any three six-unit courses numbered between 400 and 580 with ECON 500, 520, and 540 recommended

- The interdisciplinary component of the major is:
- Completion of an independent study project that has been approved by both departments.
- A major must have an advisor in each department.

### Tutorials

The department views tutorials as opportunities to enhance its usual course offerings, not duplicate them. In order to reserve tutorials for this purpose, no tutorials are given for courses routinely offered, and the department does not normally permit a tutorial to be used to satisfy any requirement for the major.

### First-year courses

The department offers two calculus sequences: MATH 140, 150, 160 (*Calculus
I, II, III*) and MATH 120, 130 (*Applied Calculus I, II*). Students intending to major
in mathematics, mathematics-computer science, mathematics-economics, physics, or
chemistry, or any student intending to take advanced mathematics courses, must complete
the Calculus I, II, III sequence. Properly prepared students should enter this calculus
sequence their freshman year. Proper preparation means strong high school mathematics,
including a pre-calculus or elementary functions course, and strong SAT or ACT scores.
Students who lack this preparation yet need the three-course sequence should consult their
advisor and the mathematics department as soon as possible.

The *Applied Calculus I, II* sequence does not prepare students for more advanced courses
in mathematics but does help prepare students for advanced work in the social and life
sciences. This sequence demands less technical proficiency than does the *Calculus I, II, III*
sequence. Good performance in high school mathematics through the junior year should be
adequate preparation.

### Advanced Placement

Advanced placement in the *Calculus I, II, III* sequence and up to 12 Lawrence units may
be obtained by presenting a score of 4 or 5 on the AB or BC calculus exams administered
by the College Board or by performing well on an exemption-credit exam given by the
department during Welcome Week. Consult the department for details. Students intending
to enter *Calculus I should not take the department's exemption-credit exam. Advanced placement and six Lawrence units (for CMSC 150) may be obtained
by scoring 4 or 5 on the A or AB College Board computer science exam. Consult the
department for proper placement.*

Six Lawrence units (for MATH 107) may be obtained by scoring 4 or 5 on the College Board statistics exam. Consult the department for proper placement.

*### Off-campus and cooperative programs

Students wishing to combine a liberal arts degree with engineering should consider the 3-2
program in engineering.

The department encourages students to apply to the many Research Experiences for
Undergraduates (REU) programs funded by the National Science Foundation; in these
summer programs, students are paid to participate in research teams at various campuses
throughout the country. Students may also be interested in the Budapest Semester in
Mathematics or in one of several other off-campus study options. Department faculty
members can provide details.

### Course numbering

Typically course numbered below 400 are offered each year, while courses numbered 400 or higher are offered every other year.

### Senior Experience in Mathematics

The mathematics department's Senior Experience consists of a 6-unit (typically one-term) independent study project completed in the senior year. The project must demonstrate the capacity to learn mathematics (or statistics) independently or to utilize mathematics or mathematical technique as an innovative or substantive part of a larger project.

Interdisciplinary mathematics-economics majors must demonstrate the ability to combine topics in both disciplines — bringing appropriate techniques of mathematics or statistics to bear on the study of economics, or learning mathematics or statistics suggested by economic models

Interdisciplinary mathematics-computer science majors must complete their independent study project in two parts: an independent study in the fall or winter term of the senior year (usually 3 units), followed by a presentation of their results in the winter term Computer Science Senior Seminar (3 units).

For mathematics and mathematics-computer science majors, the project must be approved and supervised by a faculty member in the mathematics department. For mathematics-economics majors, the project must be approved by a faculty member of each department and supervised by a member of one of the departments. Students should consult with departmental members in the spring before their senior year, in order to plan appropriately for their Senior Experience.
