18.03: Differential Equations

Prof. H.R. Miller, Dept. of Mathematics 2-237, hrm@math.mit.edu.

Various recitation instructors will be having question-and-answer sessions. On Tues. May 18: S. Soloviev (2-3 pm, 2-229), S. Lototsky (3-5 pm, 2-131), P. Bressler (6-8 pm, 2-135), C. Young (6-8 pm, 2-132).

A practice final exam, with solutions, is available on the exam page below. Caution: in an earlier version, the Laplace transforms of sin and cos were accidentally swapped on the "crib sheet" portion of the practice final; they have now been corrected. Further cautions: the answer given to problem 3 is wrong; the true answer is y2 = .01. Also, in 11(a), (1,1) is a saddle, not a proper node. (The solution files have been corrected.)

Changes in PS8.5: The expression in 37(d) should have a 4/pi in front of it. The picture labeled 38(c), t=.01, on the back page, is in fact 38(b), t=10. Also, the pictures labeled 38(d), t=.1, t=1, and t=10, are in fact the pictures for t=.01, t=.1, and t=1. The picture for t=10 is indistinguishable from the one for t=1. Part I problem 38 should be 8.5: 1, 4.

Correction to the syllabus: Class 39 is a course review. Correspondingly, Part I problem 39 is replaced with "nothing new."

A summary of the topics covered in the course, courtesy of Recitation Instructor Edward Early, is available here in postscript, dvi, and pdf formats.

Some Matlab peculiarities can be found here.
