happygrrl Posted May 31, 2009 Share Posted May 31, 2009 I have heard of this and have been curious.... Quote Link to comment Share on other sites More sharing options...
elise1mds Posted May 31, 2009 Share Posted May 31, 2009 My husband is a complete computer nerd and LOVES Wolfram. He's telling me tidbits all the time. The other day, he informed me how old I was. I was less than thrilled, but he wasn't trying to be horrid... just giggly about a new thing Wolfram had told him. Quote Link to comment Share on other sites More sharing options...

asta Posted May 31, 2009 Author Share Posted May 31, 2009 You're welcome. I've been wishing for something this simple for facts; DS gets "lost" in the internet. And I always want him to have multiple sources, so this will help. a Quote Link to comment Share on other sites More sharing options...
jenL Posted May 31, 2009 Share Posted May 31, 2009 I just fiddled around with it... Neat site! Thanks! Quote Link to comment Share on other sites More sharing options...
RegGuheert Posted January 5, 2010 Share Posted January 5, 2010 Thanks, Asta! DS19 noticed MomsintheGarden and DD17 struggling with some calculus solutions. He said he often pulls up the Wolfram|Alpha site when a fellow student asks him a question like "What did I do wrong?" Here's an example of using this site taking an equation from DD17's calculus: 1) Open the Wolfram|Alpha site. 2) Enter the following text into the box at the top of the page: (1+(1/(x^(2/3))))^(1/2) 3) Click the equals sign (=) to the right of the equation you just entered. This will show the equation in a form like it was originally found in the textbook as well as several interesting characteristics of the equation, including the indefinite integral for the equation. 4) The real problem in the textbook was to solve the definite integral for this equation. To do this, enter this into the box at the top instead: Integrate[(1+(1/(x^(2/3))))^(1/2),{x,1,8}] This returns the same result as that found in the solutions manual. If nothing else, you can use this website to check your solutions manual in case you suspect there is a mistake. Enjoy! Quote Link to comment Share on other sites More sharing options...
EKS Posted January 5, 2010 Share Posted January 5, 2010 My son is completely in love with this search engine. He's always showing me stuff he is doing with it. Quote Link to comment Share on other sites More sharing options...
