Please remember to do the TN Voice evaluations. I especially appreciate any comments you may have. Thanks.
The homework score will be based on a total of 250 points. The maximum possible will be 100% though. The homework is 20% of the grade.
To calculate your homework grade: Add up the three homework scores listed on your test. Also, add 10 pts. for each of the 5 group projects done and for the public key encryption - entering a key (10 pts.) and decrypting a message (10 pts.) There were over 310 total points.
Sketch a gallery with 12 vertices which needs 4 cameras or 12 vertices which needs only 3 cameras. How many cameras will you need for a gallery with 8 vertices? Can you draw a gallery with 12 vertices which needs 5 cameras? Why or why not?

You may redo one problem from test 2 on separate paper and hande it in along with the test on Friday, October 20. You can come to office hours to pick up your test or get help.
Monday Class September 8.   Since we are studying prime numbers, if both UT's and Indiana State's scores and the sum of their scores are all prime numbers, class will be canceled. (See you Monday.)
Look at the suggested problems listed in the course schedules.
The problems handed out in class on the first two days.
Text: The Heart of Mathematics, by Burger and Starbird (4th edition. We will roughly cover chapters one through four with some additional topics. There is an ebook available. See the book's web page.
Tests: There will be three hour tests, plus a comprehensive final exam.
Homework and In-class assignments: There will be about 15 assignments to be handed in throughout the term. You may collaborate on problems, but must write up your own solutions. It is important to keep up with the assignments. The best way to learn math is to struggle with lots of problems. There will also be some assignments done and handed in during class. Not all of the available points will be counted, so anyone who works faithfully at them will get a good assignments grade.
Grades: The 3 tests, the assignments and the final exam will each count 20% of the grade. Grades will be computed on the math departments scale: 90-100% A, 87 - 89% A-, 83 - 86 B+, 80-82% B, 77 - 79% B-, etc. Some consideration will be given to steady improvement throughout the term; of course consideration will also be given to a steady decline throughout the term.
Calculator: You should have a scientific calculator for this course. For example, any TI graphing calculator (the TI - 81 through 86) or Sharp or Casio is fine. Any calculator with an exponentiation key is fine, but not one built into your phone or with an internet connection. You will always be allowed to use a calculator on tests. If you don't have one, find the nearest pawn shop.
Make Up Policy: If you must miss due to a university sanctioned meeting let me know ahead of time. If you have an emergency, please notify me as soon as possible (email is best) to schedule a make-up.Last update: April 20, 2018, 3:45 pm
