### Course Syllabus: http://math.fdltcc.edu/wetherbee/m1015/

Class materials will be online on D2L under Content. For easier recollection, you can find this course from this URL: math.fdltcc.edu

### Zoom Class Meetings, Email, Videos

We are starting the semester with zoom classes and may continue using zoom through the semester. Install a zoom client on your computer with a microphone, speaker, and camera. There are zoom apps for iphone and android phones. Test zoom out between devices.

For zoom class sessions, login to D2L and note the zoom ID and password for zoom class meetings. These probably will not change for the course; I would let you know by email if there are changes.

Check your email daily! This is how I'll communicate with the entire class.

Some videos will be put online. You can check this one out to see how they play on your devices:

Make sure that you can view this. If you want to see closed captions (CC), they are in this video. Make sure that your video player can show CC if you want them.

### D2L: https://fdltcc.learn.minnstate.edu/,

Get to know your star ID and password for D2L and email, and check you email daily! Everything will be online from D2L when you login to the course.

### Textbook (Free online; inexpensive in the FDLTCC bookstore)

Trigonometry, by Michael Corral
Textbook Web Site: http://mecmath.net/trig/
The bookstore ordered printed copies, and these are relatively inexpensive.  However,
this book is also free.

Local PDF of textbook :

### Calculator

You may have a calculator already, but make sure that it is a scientific calculator. If you need to buy one, I recommend a cheap calculator like a TI-30XS Multiview. This does what you need, and the bookstore sells them for under \$20 . If you have a problem getting one, let me know. You need to have it available for all assignments. You do not need a more expensive graphing calculator, but, if you have one, it will be fine.

### SageMath: SageMathCell

This is software like Mathematica and Maple which can do symbolic algebra, graphing, and many other mathematical things, but SageMath is free. A jupyter notebook with SageMath should be available later in this course; in the meanwhile, SageMathCell from the link above works well.

### 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.
