The sequence 216&417 emphasizes problem-solving and applications and is intended for students of engineering and the sciences.  Mathematics majors and other students who have some interest in the theory of mathematics should elect the sequence 217&316. Math 216 is a basic course on differential equations, intended for engineers and other scientists who need to apply the techniques in their work. The lectures are accompanied by a computer lab and recitation section where students have the opportunity to discuss problems and work through computer experiments to further develop their understanding of the concepts of the class. Topics covered include some material on complex numbers and matrix algebra, first and second order linear and non-linear systems with applications, introductory numerical methods, and elementary Laplace trans- form techniques.

### Math 217 - Linear Algebra

Prerequisites: Math 215 or 285 4 Credits.  No credit granted to those who have completed or are enrolled in Math 419 or 420. 2 credits granted to those who have completed Math 214 or 417. For a student who has completed the calculus sequence, there are two sequences which deal with linear algebra and differential equations:  Math 216 & 417 (or 419) and Math 217 & 316. The sequence 216 & 417 emphasizes problem-solving and applications and is intended for students of Engineering and the sciences. Mathematics majors and other students who have some interest in the theory of mathematics should elect the sequence 217 & 316. These courses are explicitly designed to introduce the student to both the concepts and applications of their subjects and to the methods by which the results are proved. The topics covered include: systems of linear equations; matrix algebra; vectors, vector spaces, and subspaces; geometry of Rn; linear dependence, bases, and dimension; linear transformations; Eigenvalues and Eigenvectors; diagonalization; inner products. Throughout there will be an emphasis on the concepts, logic, and methods of theoretical mathematics.

### Math 285 - Honors Multivariable & Vector Calculus

Prerequisites: Math 156, 176, 186, or permission of instructor 4 Credits.  Credit is granted for only one course among Math 215 and 285. The sequence Math 185-186-285-286 is an introduction to calculus at the honors level.  It is taken by students intending to major in mathematics, science, or engineering as well as students heading for many other fields who want a somewhat more theoretical approach. Although much attention is paid to concepts and solving problems, the underlying theory and proofs of important results are also included. This sequence is not restricted to students enrolled in the LS&A Honors Program. Topics include vector algebra and vector functions; analytic geometry of planes, surfaces, and solids; functions of several variables and partial differentiation, maximum-minimum problems; line, surface, and volume integrals and applications; vector fields and integration; curl, divergence, and gradient; Green’s Theorem and Stokes’ Theorem.

### Math 289 - Problem Solving

Prerequisites: None. 1 Credit. May be repeated for credit One of the better ways to develop mathematical abilities is by solving problems using a variety of methods.  Familiarity with numerous methods is a great asset to the developing student of mathematics.  Methods learned in attacking a specific problem frequently find application in many other areas of mathematics.  In many instances an interest in and appreciation of mathematics is better developed by solving problems than by hearing formal lectures on specific topics. This course is intended for students who are enthusiastic about doing mathematics and solving challenging problems. It is not restricted to honors students. This course is excellent preparation for the Putnam competition. Students and one or more faculty and graduate student assistants will meet in small groups to explore problems in many different areas of mathematics. Problems will be selected according to the interests and background of the students.
