For a limited time only:
Lecture notes on Nondimensionalization for Springs Note the typo on the first page: the dimensionless equation should have a SECOND derivative with respect to tau (NOT a first derivative).

Homework: Assignments will be made in class. Check CANVAS for assignments and writeup due dates.

Writeups:
Writeups should be legible, with explanations and intermediate steps included (if only the answer is written, you get no credit). Each assignment should be stapled together, even if it involves two or more sections from the text.

Due dates and problems for homework writeups are posted on CANVAS.

Prerequisites: You should have completed a one-semester course in linear algebra and at least two semesters of calculus. You need to have access to a computer to aid in solving equations (algebraic and differential) and to do some simple programming (Mathematica is fine). You must be able to use technology to find real or complex eigenvalues and eigenvectors of a matrix.

Some formulas you'll be using: Derivative and Integral Formulas
I expect you will have these memorized and be able to use most of them readily.

Text: Differential Equations: A Modeling Approach by Glenn Ledder, possibly with supplementary material to be distributed in class.

What I expect from you:

• Attendance: What would this class be without you?
  If you absolutely cannot make it to class, please let me know beforehand or as soon as possible after class. You are responsible for getting the notes and announcements from another member of the class (preferably two), for completing any examples from class, reading the text, and completing the homework problems before the next class meeting.
• Participation: Participation includes asking questions and "what if ... ?", as well as responding to my questions and working in groups. Please help me keep the other students awake. If the instructor falls asleep during class, everyone's class grade will be lowered one full letter grade.
  
• Reading: Reading assignments will be made at each class meeting, and should be completed before the next class meeting.
  
• Homework: Do it! I will always allow at least one day between assigning problems and collecting the writeup, so you can ask me questions BEFORE the day it is due. I will let you know when a formal writeup is required.
  

Assessment:

• Homework will be assigned regularly in class. Regularly (approximately weekly) formal homework writeups will be collected or the homework will be quizzed.

• You will choose a modeling problem, research it, and present the modeling and solution, roughly 5-10 typewritten pages plus computer output and graphs. More details on requirements and possible project ideas will be made available.

• There will be two or three one-hour in-class tests.

• There will be a comprehensive, two-hour final exam. I think.

Grade:
Homework: 15%
Project: 15%
Tests: 40%
Final Exam: 30%
