Here is a selection of the June 2013 Calculus 12 Final Assignment videos...
A great video, but with one silly/simple mistake. Can you find it?
Another good video, but for such a simple problem, more detail could have been put into the explanation.
Some good visuals and the problem is clearly explained, but with such a simple problem, it would have been good to see more detail and depth in the explanation.
A well explained and very detailed video--but far longer than it was supposed to be!
Some funny visuals, but the actual problem is a little hard to hear and the explanation would benifit from more visuals--maybe a graph of the cost function?
