Question 257513
Try youtube.  I know people usually think of youtube as a social sight for people to post random videos, but there is a LOT of educational videos as well.  I have found it as an extremely useful resource when covering a broad range of math topics.  Search for key words such as:  conic sections, vertex form, and any other key words that are in your chapter.  There are some very good videos and some that are poor quality.  Use the suggestions after each video to go to related videos.  Although I do not usually refer people to youtube, conic sections are best explained with illustrations and youtube covers the topic VERY well.
