Chair, Professor H. T. (Pete) Hayslett

The Department of Mathematics offers courses in mathematics and statistics for students who: (1) plan a career in an area of pure or applied mathematics; (2) need mathematics as support for their chosen major; or (3) elect to take mathematics as part of their liberal arts education or to fulfill the area requirement in quantitative reasoning.
The department offers three programs: majors in mathematics and mathematical sciences and a minor in mathematics. Majors in mathematics and mathematical sciences can be taken with honors. In addition, there are interdepartmental joint majors in economics-mathematics and philosophy-mathematics.
Colby mathematics majors in recent years have entered graduate school to do advanced work in mathematics, statistics, computer science, biomathematics, and physics. They also have used the major as a solid foundation for careers in teaching, law, banking, insurance, management, the computer industry, and other areas.
All students who intend to enroll in one of the 100-level calculus courses are required to complete the mathematics placement questionnaire prior to registration.
Requirements for the Major in Mathematics
Completion of one year of calculus, Mathematics 253, 262, 274, Computer Science 151; one course (to establish an overall "theme" for the major) selected from Mathematics 311, 381, 398, Computer Science 231; four three- or four-credit courses selected from mathematics courses numbered 200 or above (excluding Mathematics 484). With written permission of the advisor, one (or two, in exceptional cases) of these courses may be replaced by a course with significant mathematical content from another department.
Requirements for the Honors Program in Mathematics or Mathematical Sciences
Requirements for the Minor in Mathematics
The point scale for retention of the majors and minor applies to all courses in the majors/minors. No requirement for the majors or minor may be taken satisfactory/unsatisfactory.
 Calculus with Precalculus I Designed for students who enter Colby with insufficient precalculus background for the standard calculus sequence. It is expected that all students who complete Mathematics 101 will enroll in Mathematics 102 in the following January. The combination of 101 and 102 covers the same calculus material as Mathematics 121. Completion of 101 alone does not constitute completion of a College calculus course for any purpose; in particular, it does not qualify a student to take Mathematics 122 nor does it satisfy the quantitative reasoning requirement. Students electing this course must complete the mathematics placement questionnaire prior to registration. Three credit hours.

121fs Single-Variable Calculus Differential and integral calculus of one variable: limits and continuity; differentiation and its applications, antiderivatives, the definite integral and its applications; exponential, logarithmic, and trigonometric functions.
