Mathematical Methods for Engineers II

Feb. 25, 2013: We will have a quiz next week (week 8) in the lab sections. The quiz will cover higher order linear ODES and system of 1st order linear ODES.

Final Exam: Thursday, March 21 from 4:00pm to 7:00pm

Jan. 30th, 2013: We will have our midterm exam on Feb. 12th during the regular lecture time. The exam covers everything we learned on 1st order and 2nd order ODES. Note that AMS20A students are not required to take the midterm exam.
