 TUTORIALS start during the SECOND week of classes
 TEXT: Differential Equations and Boundary
Value Problems (3rd ed.) by Nagle, Saff and Snider.
 SYLLABUS: First and second order equations, linear
equations, introduction to systems of differential equations,
applications, series solutions, elementary numerical methods,
Laplace Transforms. Text: Chapters 18
 ASSIGNMENTS: There will
be 8 assignments; the first four will be webwork assignments, the
last four will be regular, "pen and paper" asignments.
 MIDTERM: There will an inclass midterm on October 24.

Monday, December 9, from 6:00pm to 9:00pm, in Burnside 920.
 OLD FINALS: Go to
SUMS, then click on "Resources" and on "Math Exam Archive."
 GRADING: If A = assignment mark, M = midterm mark,
E = exam mark and F = final mark (all out of 100), then F is the
larger of .85E + .15A
and .6E + .25M + .15A
 All final grades have been entered on banner. You can look up
your scores on webct (best percent, out of 100). The letter grade follows
the usual McGill convention. The mean score is 79.9, the meadian is 85.1
