Emath1 Lab Summer 2008

Current Schedule with Assignments

Homework Server You get five attempts on each homework assignment.

Lab Server You get the same type of problem over and over until you get it correct.

Bookmark these pages, they run independently of everything else. If your fsu id is abc08z and your fsusn is XY7654321, then your login will be abc08z and your password abc4321. You can find your FSUsn here

FAQ on mapleTA. There are several things that can cause confusion about the way mapleTA shows the correct answers.

• mapleTA will show the the answer to sqrt(2) as 1.414214 plus/minus 0.001 but the plus or minus sign is not part of the answer. Instead it is telling you that your answer must be correct within a 0.001. So if you answered 1.41, it would be marked wrong and if you answered 1.41455555 it would be marked correct
• mapleTA will add comma's to answers to mark the thousands and millions etc. These are not part of the answer. If the answer is 1234567, mapleTA will claim the answer is 1,234,567 but will mark 1,234,567 as incorrect.
• The lab portion gradebook will sometimes make it look like you only have partial credit, for example claiming 1/2. Do not believe it, the one on the top says you have full credit, the 2 on the bottom says it took you two tries. The number of tries does not effect your grade.
• Only the best grade counts, if you get a 0 after getting a perfect score, your grade is still the perfect score.
• MapleTA is not the same thing as Maple, it is incorrect to shorten MapleTA to Maple.

Our homework problems generate lots of computation, sometimes the server is slow to present the problem. Sometimes it stops and needs to be given a kickstart, do not count on the server being available at the last minute.

READ THIS

If for some reason the server is not working, immediately email bellenot with a careful description of your problem. Include exactly where the error occurred and what the error message was. Do not assume that someone else also has the same problem or error.

Your private gradebook This has a username password which will be given in class. [You will also have to add your-code.html to the url above.]

The free fsu email account are now managed from the FSUID site, this link will point you in the correct direction. You can have your email forwarded to your favorite ISP or you can read your mail directly from the web from this link or you can read your fsu email by several other methods.

Emath1 Lab is an experimental class and is still evolving. Here is the link for the version taught in Spring 08

• A large collection of handouts will eventually appear in this directory
  • Reduce Row Echelon Form Summer 08 version
  • Iterative L-values and E-vectors For scilab2.
  • Plotting ax^2+2bxy+cy^2 = 1
• Scilab will be used in this course, it is free and availible from Scilab Home Page we have some Hints and the local scilab directory.
  • Mac OS X users. Scilab requires that you install X11 on your computer. X11 is in on the Mac OS X install dvd, but it is not always installed by default.
  • Mac OS X 10.5.2 users: the versions for 10.4 work on 10.5.
• FSU computer lab Page
• FSU Math Tutor List
• The MAC1140 practice server has matrix problems in chapter 10. Select mac1140 as your class class and then
  • 1140Q10.1 for 2x2 number of solutions problems (0, 1 or infinity)
  • 1140Q10.2 for 3x3 number of solutions problems (0, 1 or infinity)
  • 1140Q10.3 for 3x3 rref solutions
  • 1140Q10.4 for determinants
  • 1140Q10.5 for inverse matrices
  Professor Stiles has on-line notes for this class which are weakly password protected. This user/passwd can be found on-line but it will be given in class.
  • Systems of Linear Equations in Two Variables
  • Linear Systems in Three Variables
  • Matrices
  • Determinants
  • Matrix Algebra
• Maple (Maple is a trademark of Waterloo Maple) dir with example files
• Octave (like Scilab) is another free matlab clone Octave home
