[Suman Ganguli]

As I mentioned in class, there are a ton of online resources that you can use to help you learn the course material. I will try to pick out specific things and post them to the course blog (http://openlab.citytech.cuny.edu/gangulimat1375spring2013/), but in the meantime you should take a look at the following:

1) Khan Academy’s Algebra & Trigonometry/Precalculus sections:
https://www.khanacademy.org/math/algebra
https://www.khanacademy.org/math/trigonometry

2) Coursera is coincidentally running a free precalculus MOOC (http://en.wikipedia.org/wiki/Massive_open_online_course) right now. Although it started a few weeks ago, you can still sign up and have access to their course materials:

Let me know if you find these materials useful, and if so which ones (post a reply below!)
