 Grading: The course % for each of
M450 and M451 is determined by:

   Midterm       M            100 
   Final         F            100
  Homework      HW           200

         % = (M+F+HW)/4

The final is not comprehensive.

The midterm exams is in class.
A single sheet of notes will be
permitted. The Final is take home
and due at the date indicated below. 

Midterm: TBA (in-class)

Final: TBA (take-home)

Homework due dates and exam dates will
be announced in class and posted
here at a later date. Exam content
will also be announced in class.
 Syllabus: Material for the M450/M451 sequence
will be selected from:

 Class Notes ODE Review
Chapter 1 Dimensional Analysis
Chapter 2 Perturbation Methods
Chapter 3 Calculus of Variations

Chapter 4 Eigenvalue Problems, Green's Functions
Chapter 6 Partial Differential Equations
Chapter 7 Wave Phenomena
Chapter 8 Models of Continua

Homework: Assigned homework and some of their
solutions will be posted below as the
course develops.

Homework scores will vary depending
on their length and difficulty.
The raw scores will be summed,
and converted into a % to yield
the 200 points in the final grade.

Homework and Exams for M450/451:

Below are the homework assignments and take-home exams. In the "Sample" column I will occasionally post old versions of similar assignments and their solutions. These should help augment your notes with more worked examples.

Samples Due Date Content  Solutions
HW 1    Wed. Sept. 17 ODE Review  
HW 2
Mond., Oct 2 Dimensional Analysis
HW 3    Wed. Oct 18 Regular Perturbations

Midterm   TBA You will be permitted a single (2-sided) sheet of notes.
The exam will consist of four questions from:
  1. Dimensional Analysis - Buckingham Pi theorem
  2. Nondimensionalizing an ODE(s) system
  3. Regular expansions of f(x,epsilon)=0
  4. Regular expansion of a system 
  5. Regular expansion of an IVP
The questions will be computationally simple so all can
be done in 50 minutes.

HW 4     Poincare Lindstedt method, asymptotics, singular
root approximations, Singular boundary value prob.
HW 5     Nonlinear BVP, functional First Variations, Simple Euler Lagrange equations.
