Welcome to the home page for section ES31 of MATH-1200 (Trigonometry) at Southeast Community College in the Winter term of 2014. I am Toby Bartels, the instructor.


Here are some useful links for the administration of the course:


If you miss a homework assignment, then you can find it here. Eventually some solutions to graded homework will show up here too. Although only homework and the final exam contribute directly to your grade, attendance is also important.


The official textbook for the course is the 9th Edition of Algebra & Trigonometry published by Prentice-Hall (Pearson). You should be able to get this at the bookstore, and the homework problems will come from it. (This same book is used for MATH-1150 too, so you might want to check both shelves in the bookstore.) You will also need to buy access to MyMathLabPlus; see the instructions below.

I may also have some notes for lectures, hand-outs, and so forth. If you missed class, then you might be able to find a substitute here. But there is no guarantee that everything will show up!
