#### Calculators, Computers, PEDs (Personal Electronic Devices)

The TI 83+ and 84 are the most popular TI models, but the TI 85 and 86 also work well. Casio also has nice graphing calculators. The TI 89 is harder to use for this class and is just about the same cost as a mini-notebook computer which can be loaded up with free and better mathematical software. If you don't have one already, get a cheap calculator and bring it to class. The TI-30 is popular and costs somewhere in \$6-20. You can use these for exams and quizzes.

Do not play games, email, text, chat, surf, talk, etc. etc. on your PEDs. Turn these things off during class and put them away. At times a PED, laptop, or other computer device may be useful in class. Still, turn them off and put them away until you are told when they will be useful and allowed. PEDs and computers are not allowed for exams or quizzes.

#### SageMath: math.fdltcc.edu/sagemath

This is software like Mathematica and Maple which can do symbolic algebra, graphing, and many other mathematical things, but SageMath is free. You can download it yourself from sagemath.org then install on a Gnu/Linux machine, but it is probably easier to use the FDLTCC server above.

You can also use URL https://math.fdltcc.edu because this is a secure connection which is redirected from http://math.fdltcc.edu/sagemath; the "s" after "http" means secure. You may be told that there is no security certificate, and there is not one yet for this web site. You can safely add an exception for this sagemath website to just do math. (You should never do this for online banking or any other online service which handles anything personal which must be secure.)

Note that these are class accounts, so everyone will be able to see work done by everyone else. There is no privacy. Put nothing private or even identifiable to yourself online--which is excellent advice for everything on any Internet service. Make up worksheet names which you can remember yet which are not identifiable to yourself, and use these just for math.

#### The Course

This course addresses FDLTCC liberal education requirements (Competencies Across the Curriculum) in problem solving and technology. You should come to class everyday! This is the easy way to do well in any course, and it is especially true for math classes. There are exercises in the text for you to do, and these are usually answered at the end of each chapter. You will also get homework assignments on handouts, and you should complete then hand these in at the beginning of the next class. You homework grade is based on completing and turning in these homework handouts. You will also get sample exams which will be similar in length and content to the in-class exams. Let me know if there is are accommodations you need for the class.
