Course Description: This course is a continuation of Math 2030 with an emphasis on foundations and the theory of vector spaces and linear transformations. Additional topics include inner product spaces, symmetric and orthogonal transformations, bilinear forms, similarity and diagonalization, the solution of linear differential equations, and various applications in mathematics, physics and computer science.

Linear combinations and span, subspace axioms, intersection of subspaces. Linear dependence and independence, bases, replacement lemma, dimension. Linear functions, kernel and image, rank and nullity, dimension theorem. Matrix of a linear map, change of basis matrix. Determinants. Complex numbers.

Eigenvectors, eigenvalues, and diagonalization. Algebraic and geometric multiplicity. Diagonalization of hermitian matrices. Solution of linear differential equations.
Course Work:	There will be an in-class midterm and a final exam. The midterm is scheduled for Thursday, March 2 in class. The final exam will be scheduled by the registrar's office. There will also be weekly homework, to be handed in at the beginning of class on Thursdays. From each homework set, I will choose some number of problems that will be graded. Late homework will not be accepted except with my prior permission. Each week, you will also be assigned some reading from the textbook.
Marks:	Marks will be based on the homework, midterm, and final exam. Class participation may be taken into account. The homework counts 25%, the midterm counts 25%, and the final exam counts 50%. You need to pass the final exam in order to pass the course. Numerical grades are converted to letter grades via the Dalhousie Common Grade Scheme: 90–100 = A+, 85–89.9 = A, 80–84.9 = A−, 77–79.9 = B+, 73–76.9 = B, 70–72.9 = B−, 65–69.9 = C+, 60–64.9 = C, 55–59.9 = C−, 50–54.9 = D, 0–49.9 = F.
Missed test policy:	A missed midterm cannot be written at another time. If you miss the midterm without my prior permission, then it will count as a 0. Exceptions are made in two cases: (1) if you obtain my prior permission to miss a midterm, or (2) if you have an officially valid excuse such as a medical doctor's note. In these cases, the weight of the missed midterm will be shifted to the final exam (i.e., the final exam will then count 75% instead of 50%). A missed final exam can only be made up if there is a valid medical excuse.
Note taker sought:	A note taker is required to assist a student in this class. There is an honorarium with some conditions. If you are interested, please go to the Advising and Access Services Centre, Killam G28 for more information or send an email to notetaking@dal.ca.
