New source of inspiration/data

[accessD]

Hi

Recently a friend of my asked me how to draw simple sine wave in Xara.

After a minute I came up with a pretty unusual solution.

I advised to visit http://www.wolframalpha.com and enter sin(x) expression in "compute" field.

At the bottom of the result page is "Download as: PDF" link. After saving resulting PDF on disk you can reopen it in Xara, and extract desired sine wave from drawing by removing ClipViews and Groups.

WolframAlpfa is computational knowledge engine. It can provide many other data like charts, plots, equations, stocks, weather conditions, maps, orbits, chemistry data, fractals and many, many more..

I recommend to visit their Visual Gallery of Examples http://www.wolframalpha.com/gallery.html

BTW, you can generate spirals there )

Cheers
