I know this post comes 1 year late, but I really have to let you guys in on my find after trying out this site. In the past when I was doing my degree studies, searching for formulas and statistics was always a hassle as you have to to review links from search engines individually. Now we are can search for such computational knowledge “EASILY” as this site gives us the direct answer rather than forcing us to flip through the numerous pages of search results before we find the “Ah-Ha” answers.
Wolfram Alpha doesn’t solve all our problems in life but when we need some formulas we know Wolfram Alpha is there. Check it out.
