Dear Mr. Buzing,
yes, I'm using Mathematica and its Alpha function. Using math function is no problem; yet when I use free form function like" plot sin(x)", or Alpha function like " population of the world", it responded "Request denied by Wolfram/Alpha server (3004)"
I'm able to access. http://www.wolframalpha.com website; yet in my computer it shows the above denied message whenever I use Alpha function. Thank you for your help.
