26 APR I posted solutions to Homeworks 1-7 on the class website, which is at https://www.math.lsu.edu/~malisoff/7390/. Those are the same solutions we went over in class. If you had any questions about how to do any of those homeworks, please check those solutions or feel free to ask me any questions. As announced previously, each problem on each homework is graded out of 4 possible points, and your grade on a given homework is the letter equivalent of the average of your grades on the individual problems on that homework, where 3 or 4 points is an A, 1 or 2 points is a B, and 0 points is a C. I round up, so for example, if your scores on the individual questions on a homework were 3 and 0, then I round the 1.5 up to a 2, so you get a B on that homework. Even if you don't know how to solve a homework problem completely, you should turn in the work you did on the problem for possible partial credit. I also posted the questions for Homeworks 8 and 9 on the website. Those homeworks are due next week on Tuesday and Thursday, respectively. I also posted the notes for Lectures 1-19 on the website. Lecture 19 is the lecture for this coming Tuesday, which you should try to read before Tuesday's class, if possible. On Tuesday, I will distribute the questions for Homework 10, which counts as the final exam for our course. I will also distribute 2 extra credit homework assignments, Homeworks 11 and 12, which will be graded using the same grading scale as the other homeworks. Your course grade will be determined by computing your homework averages in two ways. First, I will compute your average grade of your best 8 of the first 10 homeworks, so I drop the two lowest homework grades among the first 10. Then, I will compute your average grade of your best 10 homeworks out of the 12 total homeworks, including the extra credit homeworks. Whichever of those two homework averages comes out higher will be your course grade. This means that doing the optional extra credit homeworks can help your grade, but it cannot hurt your grade. As another hint for how to solve #1 from Homework 8, you should try to solve for the unknown function \zeta by solving a differential equation that \zeta must satisfy. Two of you asked me for graduate assistant jobs working for me. You can read about the jobs at https://www.math.lsu.edu/~malisoff/JobAd.txt. I will be happy to talk with any students interested in being considered for those jobs as soon as our course lectures end. Also, the mathematics department asked me to teach a marine robotics course this coming fall, which you can read about at https://www.math.lsu.edu/grad/outlines2014-15#4997-3f14. For planning purposes, please let me know whether you plan to take that fall course of mine as soon as you decide. I hope all of this information is helpful to you, and that you are enjoying this course as much as I am enjoying teaching it. 29 JAN The deadline for adding courses and registering late has been extended to 4:30 p.m., Friday, January 31. 26 JAN There were several calculations in the lectures that students were asked to verify on their own. Details on how to do all of those calculations have been posted in the lecture notes on the class web site. All students are encouraged to check for those lecture notes if they have any questions about those calculations. 24 JAN Due to the university closure on Friday, January 24, 2014, the deadline for adding courses and registering late has changed from 4:30 p.m., Monday, January 27 to 4:30 p.m., Tuesday, January 28. Please pass this information along to any students you know who were considering adding this course for credit. 21 JAN Notes for Lectures 1-2 are now on the class web site. You are encouraged to read Chapter 17 from Reference 1 on the syllabus sometime over the next week, since that is the next block of material that we will be covering. That reference is available for free from http://www.lib.lsu.edu/ if you connect to that site on the LSU campus. 16 JAN Welcome to the class. The syllabus is on the class web site and will be distributed in class. The class web site also has answers to frequently asked questions.
