# ญญญญญMath 313 Syllabus and Homework Assignments (Prof. Lushnikov),  Spring 2023

Column Date below is filled with dates for sections I (Prof. Lushnikov)  finished lecturing on. BC means Brown and Churchill's book. Homework is due each Tuesday on learn.unm.edu for all sections assigned from the previous week. For your convenience I also include due date for each homework assignment in column Due date.  I recommend to read sections before I actually lecture on them. You might not understand them well, but you can find out the main concepts and have some questions already in mind when you listen to lectures.  Only a fraction of homework problems will be graded. Currently there are sections listed for all the material I plan to cover in Brown and Churchill's book. However, I might decide to change some of them as the semester progresses, perhaps even adding or deleting a section here and there. So please return to this page periodically to make sure you are working the correct homework problems. Solution will be posted only to problems without answer key in BC.
