I enjoyed this article very much. The combination of history, that I love, with algebra, that I struggle with, made my understanding of the concepts of functions easier. I especially appreciated seeing the conics sections and the application of each into graph equations. You all gave me an "aaha" moment. Keep up the good work. Debra
