• Files to look at in connection with Math 308: A very brief overview of Maple and DE's
This is a bit out of date, as the examples refer to Maple V release 3.
• Postscript version of the syllabus here.
• Euler's method.
• The many faces of a differential equation, seen through various Maple-lenses.
• Commentary on exam 1. Text discussion of all five problems here, (or ascii version ) with a Maple sheet (or text version for problem 5. To print the text version, follow the instructions given in the Calclabs page. The URL address is http://calclab.math.tamu.edu/docs/labdocs/howtoprint.html, or perhaps this link will get you there.
• Heating and cooling. Maple sheet ( ascii version .
• The falling rock, Another Maple sheet. This one discusses the physics and illustrates the various things that can be done with Maple. I left in a slew of Maple wrong turns, and showed how I got back on track. You cannot let yourself get rattled by a barrage of error messages.
• Maple implementation and Maple text version of the second order Taylors and Runge-Kutta methods.
• Maple sheet relating to the Wronskian and interleaving .
• Maple sheet relating to complex numbers.
• Editorial column on labs excerpted here. Postscript version here. If you have something to add, please email it to me: Doug.Hensley@math.tamu.edu.
• Exam 2 will be held on Friday March 7, covering topics to date through and including section 4.10 (Note restriction of topics.)
• Maple sheet: systems of first order differential equations and demographics . (A counter-Malthusian perspective).
• Posting of examples from review for exam 2...this is short on text; if you were in class you'll know where the questions came from. Text file here.
• Maple text file relating to the second exam.
• Maple text sheet and part two relating to linked system vibration.
• Maple text file related to phase plane analysis.
• Maple text file related to the Laplace transform and solving heat diffusion problems.
• Maple sheet and text file concerning convolution and the Laplace transform.
• Maple sheet with solutions to the exam.
• Next material is chapter 9, leading eventually to chapter 12: we're omitting the last bit of material on the laplace transform. Homework over this topic will be due Fri Apr 16, rather than Monday, so you'll have a full week.
• 9.2 # 2, 4, 6, 10, 18a, 20, 26, 30, 38, 42, 44 9.3 #1, 2, 4, 8, 10, 14, 18, 20, 24, 26
• Last homework assignment is the original final homework assignment from ch 12. All of it, not just the (nonexistent) even problems.
• Maple sheet related to stability.Updated version, Maple file.
• Monitors. Read about the choices. Email me your opinion.
• Critical values and local behavior of systems.
.
• Maple file and text version with some review questions. Maple file and related text file.
• Further materials for math 308.
• Review. All the stuff on this page is relevant. But here's the first sections of that review page. I wrote it as a Maple file; that way it's "live". This file is under construction and will grow over the next few days. NEW: Maple executable file.
