As i first went to the website, i noticed that there was a menu bar on the left, i continued on to find many different types of demos that was stored for Calculus, and Pre-Calculus. I was amazed as to the animations and pictures, along with though rough explanations on their demo. I followed along easily with the information that went along with the demo, i especially liked in "how a carpenter draws an ellipse" it showed real life examples arches that is made by use of an ellipse. For first time users, i think using this material can really benefit a student/teacher learning great examples for their subjects.
For first time users i think that it should be easy enough to access the demos because of the menu bar on the left that categorizes the site's contents.
