Customer Reviews


This course is really amazing. I'm going to check out if I can take it through iTunes u for credit. The quality is exceptional and the material is well put together. It"s amazing that a Community College is leading the way. You've definitely set the standard! I hope I see the textbook available through iBooks soon.


I'm using this in conjunction with my regular trig class (we use the same book and my instructor is not easy to follow). Mr. Rosenberry goes into detail about where everything comes from so you really understand what's going on. You can tell his students really GET it which always a good sign!

I contacted him about a missing video and he responded the next business morning...quicker than my own instructors!

I highly recommend auditing this course for trig students!

Wow excellent!

I haven't had time to check out all the other courses available on iTunes u but I thought start with a topic that I hadn used in A while. Notes videos and app suggestions are useful. Seems like a very thorough course.
