Hi , I came across the website https://mathworld.wolfram.com , while searching for varied topics in mathematics and theoritical computerscience. Its , the ultimate website for people researching in applied as well as well theoritical branches of computerscience. Among the other Websites which I came across, Wolframresearch ranks the best, since it is a comprehensive site, which provides maximum details about the subject. Abstract concepts in Three dimensional analytical geometry , such as Ellipsoids, praboloids and skew lines and lucidly explained with the aid of three 3D- graphs and can be viewed as Applets. The topics covered exhaustively in the site includes Algebra, Applied Mathematics, Discrete Mathematics, Topology, Probabilty and Recreational mathematics. Apart from these features the site also has reserach findings, publications and updates on other disciplines such as astronomy, physics and biography. Wat’s more, if you are interested , you can also contribute material to this Website.n addition to this, the website also has links to related websites on Mathematics. The main features that I had found very helpful, than compared to other similar Websites is that, most of them do not cover the relevant topics exhausitvely, and also there would be lot of deviation from the main topic.But in the Wolfram research site, since there is multiple categorization, all the details have been carefully categorizes, so we can get access to specific information easily and promptly.But one disadvantage which I found was, the 3D graphs are Applets, so you cannot view them off-line , we can download only the textual details and definitions.
