Best of luck to all, and enjoy your summer.

Take care,

OpenLab #4: Advice for the future

(Due Thursday, 5/22/14, at the start of class).  Imagine that you are invited to speak on the first day of MAT 2680, to give advice to entering students.  Write at least three sentences responding to one or two of the following, describing what you would tell them.

  1. What do you wish that you had been told at the start of this class, to help you succeed?
  2. Choose one topic in the course that is especially challenging. Identify it, and give advice to students trying to master that topic.
  3. What is the most important prior knowledge (not taught in the class) that you need in order to succeed?  Why is it important?

Extra Credit.  Respond to someone else’s comment.  Do you agree? disagree? Have anything to add?

Final Exam Review Sheet is posted

UPDATE 5/17/14:  Corrected ALL answers to problem #17 (numerical methods).

Special Offer – 1 week only – WeBWorK RE-OPENED

Hi everyone,

All of the past WeBWorK assignments have been re-opened – this is your chance to make up for work you might have missed earlier in the semester.

They will all be closed again next Saturday night, May 10th, at midnight.

Why now? ¬†Well, you still don’t have your Exam 3 review sheet, so this gives you something to work on in the meantime (the Review Sheet will be posted later this weekend).

Why only one week? ¬†While I like the idea of giving you a chance to make up your incomplete assignments, I don’t want this to be a serious distraction as we approach the final. ¬†Also, it’s a special offer – no complaints!

Best of luck to you all,

Prof. Reitz
