Math 102

Background
Heretofore one of the requirements for the BS degree in economics was Math 103. Following discussions among members of the Mathematics and Economics Departments in the spring of 2006, Math 102 was created. This new course is not equivalent to Math 103, but starting in the 2006-2007 academic year, the Economics Department will replace their Math 103 requirement with the requirement that BS majors in economics take Math 102. However, because all Engineering majors and some Trinity College majors require Math 103, the Economics Department will continue to accept Math 103 credit in lieu of Math 102 for the sake of students who want to double major in economics and such a major.

First Offering
Math 102 will first be offered in the spring of 2007.

Unofficial Course Description of Math 102
Introduction to linear algebra including matrix multiplication, determinants, bases, and linear independence; vectors in n-dimensional space; partial derivatives; optimization up to constrained extremal problems in many variables; integration in several variables. Examples will be taken from economics. Prerequisites: Mathematics 32, 32L, or 41.
Here is a tentative syllalbus: Math 102 syllabus for spring 2007

Note for Engineering, Science, and Math Majors
Students who are considering a science major, a math major, or an engineering major should take Math 103 instead of Math 102, even if you're considering a double major with economics.

FAQs

  1. So, what's the difference between Math 102 and Math 103?
    Topics from 103 which are not covered in Math 102 include: vector fields, line integrals, surface integrals, integral theorems of Green, Gauss and Stokes. The linear algebra content of Math 102 is not in Math 103, nor are the examples from economics.
  2. What if I take Math 103, because the major I'm considering requires Math 103, and then later I decide that I want to major in econmoics?
    In such a case, the Economics Department will accept credit for Math 103 in lieu of Math 102.
  3. What if I take Math 102, thinking I will definitely major in economics, and then later I change my mind and choose a major that requires Math 103?
    For the math major, you would need to learn on your own the material on vector calculus, which makes up approximately the last quarter of Math 103; then at the end of the following semester, you will be required to demonstrate your proficiency in that material by taking the vector calculus portion of the Math 103 block final. After you demonstrate proficiency in vector calculus, the Director of Undergraduate Studies in Math will waive the Math 103 prerequisite for the major in mathematics. For other majors, such as physics, computer science, and engineering, you would have to contact the Director of Undergraduate Studies in that department to find out how to proceed.
  4. What if I'm considering an econ major, but I'm not sure about econ because I also have some interest in other majors, some of which require Math 103. Should I take Math 102 or Math 103?
    You should take Math 103 to keep your options open. In fact the combination of Math 103 and Math 104 will keep open all academic doors which may require mathematics.
