Lecture notes for each week should be posted by Thursday at 3:00 p.m. on the preceding week. Printing for Math classes is free in the Rushing Student Center, in the basement of LCB. It is recommended that you use these notes in conjunction with attending class. After each class I will post the filled-in versions for that day. At the end of the week I'll post the entire week's filled-in notes.
