Professors: John Feroeab, John McCleary (Chair), Peter C. Pappas, Charles I. Steinhorn; Associate Professor: Benjamin A. Lotto;Adjunct Instructor: Doris Haas*

Requirements for Concentration: Mathematics 121/122 (or 125 or permission of the department to enroll in 221), 91/2 units above the 100-level including 221/222, 301, 321, 361, and two other units at the 300-level. Reading courses are not counted among the required units. Work used to satisfy major requirements may not be taken NRO after declaration of the major. At most one unit at the 300-level taken NRO prior to declaration of the major may be used to satisfy major requirements.

Senior Year Requirements: Mathematics 301.

Recommendations: Majors are strongly urged to elect at least 2 units in applications of mathematics to other fields. A reading knowledge of French, German, or Russian is advised for those contemplating graduate study.

Sequence of Courses for Concentration: Students will normally elect Mathematics 121/122, 221/222, but freshman eligible for Advanced Placement should confer with the department. Election of advanced courses should be made in consultation with a departmental adviser.

Prospective majors in mathematics are strongly advised to complete Mathematics 121/122 or Mathematics 125 by the end of the freshman year and Mathematics 221/222 by the end of the sophomore year. In any case, the first sequence must be completed by the end of the sophomore year in order to declare the major and Mathematics 221/222 must be completed by the end of the junior year.

Advisers: The department.

Correlate Sequence in Mathematics: Students majoring in other programs may complement their study by electing a correlate sequence in mathematics. Course selection should be made in consultation with the department and the major adviser to ensure exposure to the mathematics most useful to the field of concentration.

Requirements for the Correlate Sequence: Mathematics 121/122 (or 125 or permission of the department to enroll in 221), 4 graded units above the 100level including 221/222 and 1 unit at the 300level.

Advanced Placement: Students receiving 1 unit of Advanced Placement credit based on either the AB or BC Mathematics Advanced Placement Examination or the calculus credit examination administered by the Department of Mathematics may not be granted credit for Mathematics 101 or 121.

The department recommends that students who have earned a 4 or 5 on the BC examination enroll in Mathematics 221. Students with a 5 on the AB examination or a 3 on the BC examination generally are advised to elect Mathematics 221 also, after conferring with the department. Students with a 4 on the AB examination ordinarily are advised to enroll in Mathematics 125, but should consult with the department.
