I feel like my brain is mush. I spent 30 minutes at this site going to, playing with or what ever I was suposst to do to the different curves. Although, I spent most of the time trying to figure out why this curve thing is so important. Am I just not a math person or should there be some information on what curves are, some explanation on why we use them and why they are important. I feel this Famous Math Curve site was incomplete and should be geared not only for those who know about curves but those who choose to learn.
