Thanks for checking. First to clarify: when I say 'hyper tangent' this is short hand for "hyperbolic tangent" or tanh(x). WA correctly tells you that tanh(3pi) is close to 1. My apologies for not stating this explicitly in the text. Second, WA has to be coaxed a little to find ranges of data. For instance, 'GDP belgium' gives you a great graph for the past 40 years. It's not easy to limit that graph to 1986 to 2009. It is easy however, to find the GDP of belgium for any of those years "GDP belgium 1986" - for example. No doubt that WA isn't perfect. But once you get used to the query style, it is very powerful. Ha. Thanks for checking. First to clarify: when I say ‘hyper tangent’ this is short hand for “hyperbolic tangent” or tanh(x).

Hyper tangent of three times pi? The rate at which GDP has changed in Belgium over the past 23 years? Both queries give: Wolfram|Alpha isn't sure how to compute an answer from your input...

Hyper tangent of three times pi?

The rate at which GDP has changed in Belgium over the past 23 years?

Both queries give: Wolfram|Alpha isn’t sure how to compute an answer from your input…

Totally forgot to mention that. Thanks for the reminder. I updated the post, see above. Ha. Totally forgot to mention that. Thanks for the reminder. I updated the post, see above.

That's pretty unusual. It’ probably worth mentioning that the iPhone app is $49.99. That’s pretty unusual.
