Excellent! Thanks to the professors for such a great work!


Great course for Pre-Calculus Trigonometry, especially since there are so few online courses that specialize in this one very important aspect of college level math.

This was a good course overall. I feel I have a good understanding and grasp of trigonometry. I think teh real test will be when I move on to calculus and if this course has sufficiently prepared me for it.

A couple of things to note though. One there is a vast difference between the level of content covered in the video lectures and the textbook. The textbook is written very much like a traditional textbook in that the writers are experts in their field and don't really have a grasp of when the student might get lost or not understand what's going on. They simply proceed with walls of equations that will make your eyes glaze over. This, to me anyway, is part of the reason why math education so often doesn't succeed. It doesn't understand what concepts are difficult, fails to make enough tangible examples, and doesn't walk through the logic of the techniques and concepts in an easily understandable way.

Conversely, if you do endure the pain and power through the textbook reading, you'll have a broader understanding of the subject than if you primarily depend on the video lectures and quizzes. The suffering seems needless though. There are better ways to instruct in mathematics. If you're having trouble, go to Khan Academy and Math Is Fun for much better explanations of the concepts.

The second issue is the lack of a forum, either for communication with other students or the instructors. These forums are hit and miss on other Coursera courses, and can be pretty inconsistent in the timeliness and quality of responses, but it's good that you have a community that can help directly and occasionally the attention of the TAs.

Overall though this is a good course and considering how few courses there are out there that cover Pre-Calculus, I'm glad I took this one.
