Mathematics 412, Sec. 501, Fall, 2005

• Announcements
  • Dec.12: The grades on the final exam came out much higher (median = 174) than those on the hour tests, an event unprecedented in my near 30 years in Aggieland. Of course, 60 points of extra credit didn't hurt, but clearly quite a few people woke up and smelled the coffee. Also unusual were the very low homework scores; they are supposed to be higher than test scores. So, in place of the usual generous curve on the final exam, I added 45 points to everybody's total score, which I think of as 5 more points on the hour test total and 40 points on the "Homework and class participation" scores, which obviously needed to be renormed. (In previous semesters such renorming often occurred before numbers were posted.) This makes the final grade distribution almost the same as on the final exam: 8 A, 5 B, 6 lower, 7 Q-drops. Individual grades and scores will be posted on WebCT Vista later today.
  • Dec. 8: The team solutions to the review problems are now posted.
  • Dec. 4: Tomorrow (the-Monday-that-is-a-Friday) my office hour will start at 2:30 (not 10:45). I expect to be in my office at the usual time of 2:00-3:00 on Wednesday and Thursday.
  • Nov. 21: Happy Thanksgiving! I will be out of town for a long holiday weekend, starting tomorrow afternoon, so I can't hold office hours on Wednesday. Nov. 23, or Monday, Nov. 28.
  • Nov. 12: Solutions for Test B are now available below!
  • Nov. 9: Next Math Club meeting (Monday, Nov. 14)
  • Oct. 10: Office hour this Thursday, Oct. 13, is cancelled. (I will be away from Thursday afternoon through Sunday.) The Monday office hour (Oct. 17) is rescheduled for 2:00 instead of 10:45.
  • Oct. 4: Math Career Fair (Oct. 11)
  • Sept. 23: I will be unable to meet the Monday morning office hour, Sept. 26. I will be here in the afternoon (2-3 at least).
  • Sept. 16: "Permanent" office hours: M 10:45-11:45, W 2:00-3:00, R 2:00-2:50
    I will usually be in the office at the "analogous" times (F 10:45, MF 2, T 2), but with no guarantee. (At W 10:45 I have a standing appointment with a graduate student.)
  
  
• Course handout (first sheet)
• Course schedule (second sheet of handout)
• Please see my home page for up-to-date office hours.
• Homework assignments
• Instructions for using WebCT Vista to check your homework and test grades.
• Homework solutions (written mostly by David Miller, edited and published by Changchun Wang)
• Fall 2004 course page including exams with solutions.
• Fall 2000 course page including exams with solutions.
• Some old demos. (I am sorry that I have not had time to update or maintain these properly. I'll try to find time for that later.)
  • Animation of moving wave packets (d'Alembert's solution). Input only -- requires Mathematica. Do not expect Pixar quality.
    1. Introducing d'Alembert's solution: MathLily or PDF.
    2. Wave reflection: MathLily or PDF.
    (MathLily files are both valid Mathematica files and valid TeX files.)
  • Convergence of Fourier series (partial sums). Maple input and output.
    1. square wave input and output.
    2. triangle wave input and output.
  • Summability of Fourier series (Cesaro means). To be compared and contrasted with the foregoing.
    1. square wave means input and output.
    2. triangle wave means input and output.
  • Eigenvalues of a Robin Sturm-Liouville problem. Maple input and output.
  • Bessel functions and Fourier-Bessel series. Maple input and output.
• Evans Harrell and James Herod, Linear Methods of Applied Mathematics
  Rough correlation between the Harrell-Herod syllabus and ours:
  • Block 1: HH Chapters 7, 6, 8, 3, 4, 5, 1, 9
  • Block 2: [nonexistent chapter on Fourier transforms], Chapters 20, 13 (beginning only), fragments of (15, 16, 19), 2, [nonexistent chapter on Sturm-Liouville theory], 17 (fragments)
  • Block 3: Chapters 10, 11, 18, g19[=22] (beginning)
  
  
• Test solutions
  • Test A
  • Test B
  • Final Exam
• Information on how to get a minor in mathematics, or even a double major. Most science and engineering majors can qualify easily.
