Neat!
Would be nice if it had a color bar (legend) to see which color is which value, though. The red/green/blue used below the graph for the axes ranges looks like one, and that is a bit confusing.

#122I didn't see anyone mention this specific fear, but a lot of people talked about this in the context of competition with Wolfram Alpha. What I fear is that google (on purpose or not) will outshine Wolfram's offering, push W|A out of the game, and then in 3-6 years decide it is not a feature worth keeping up. Just like code search, viable companies may fail due to Google toying with their entire industry, and then Goo…
I don't think W|A is going to disappear (I work on W|A). We do a lot more than plot functions of one and two variables -- after all, Apple chose us to power much of Siri's factual question answering. We're pioneering automatic analysis of new kinds of input, from images to long-form text to raw data (what I work on). We can out-innovate Google, even if they do a really nice job of copying our old ideas. Of course, so…
Cool! Hey, a tip, and I think I mentioned this in the comment/feedback box on W|A as well:
For some reason, every time I need information that makes me think "hey this would be the typical thing I'd expect W|A to be able to answer, I've seen it answer a similar question before" it hardly ever works ...
And I think a lot of that is due to how most of the demos I've seen are somewhat USA-centered and W|A doesn't have the same data when I query it for a European (or other) country.
How does that work? Because when I use Google or DuckDuckGo and look for that nation's bureau of statistics, fact sheet, even Wikipedia, the numbers are right there. Why is that? I thought W|A is supposed to index the calculatable knowledge for me so I don't have to search for it but instead can just run calculations with it?
Or does W|A just import complete available datasets and does not scrape the web for such data (even when it's in tabular form on an official government or university site)?
In which case, please get some more of those from non-US sources. Loads of governments opened up their data sources:
http://ckan.org/ <-- Germany, Netherlands, UK, France, Canada or are you using this one already? It's CC-BY-3.0 so there's no reason not to.

#123Thank you, Google, for making me uninstall some nVidia packages from Ubuntu that were apparently stopping WebGL from working. The tool you built is also kinda nifty, and I might even use it when trying to help people online with mathematics. Nonetheless, my day-to-day search traffic is still being offloaded to DuckDuckGo and my day-to-day image traffic is still going to Blekko. It's not you, it's me.
Blekko's good for images? I gave it a few tries a while back but I got distracted by the slash syntaxes and forgot what I was looking for :) I'll give it another try.
Today I mainly use Yahoo's image search for images.
Disabling JS on Google Search (with Opera's site-specific preference or NoScript) also does a lot of good to make this once-great search engine somewhat more usable (not for the results, of course, but at least it's not continuously stealing input focus and mucking up its own search results as you try to navigate with your browser's keyboard shortcuts).

#124One simple modification. What does this look like: sqrt(xx+yy^2)+3cos(sqrt(xx+y*y))+5

#125One of the differentiating factors of Wolfram|Alpha: Gone. Google's doesn't require a 250mb plugin to become interactive (just a webgl capable browser...). And it seems to be about 8 times faster than W|A... W|A still does a lot of things other sites don't do, but it tends to be unusably slow, and inconsistent (running same query twice in a row will sometimes not give all of the same results). I figure the end is pro…
The nail in the coffin for me on W|A was requiring a login in order to copy plain text results. (Even though the same data is copyable in the DOM, they actually go out of their way to obscure it!)
I don't think people understand how noxious this registration-obession is, especially when you need utilize it to access basic functionality.
I don't really go to W|A anymore unless there's something specifically math or statistics related that I'm looking for. That action killed any kind of casual use for me.

#126Great stuff. I'd love if it kept spinning if I released the mouse button during a movement.

sqrt(xx+yyy)+3cos(sqrt(xx+yy))
