And on top of that, it also gives you the result right there on the page: http://cl.ly/0a3L0K3T2a0E350d300n
Clickable and brings you to wolfram alpha: http://www.wolframalpha.com/input/?i=sin(x)%2B1%2F2%20sin(2x...
zero-click search is an awesome feature of DuckDuckGo
WolframAlpha has slightly more sophisticated graphing calculator functionality: http://www.wolframalpha.com/input/?i=sin%28x%29%2B1%2F2+sin%...
I haven't used WolframAlpha that much for graphs but I've often been bothered by the lack of zoom, scale and pan which google seems to have solved quite nicely. Hopefully WA will do something similar in the near future.
Great. So can DuckDuckGo: http://duckduckgo.com/?q=sin%28x%29%2B1%2F2+sin%282x%29%2B1%...

No, I don't see a fast interactive graph when I clicked on that link.
The easy zooming and panning makes this a better graphing experience than any other calculator/software I have used so far. True, you don't have the capabilities of Mathematica available, but it seems to work great for graphing a single variable function.
Related is also navigation in maps-software. Not many programs do this right even though it's so simple.

Sadly, google's cannot be used to calculate 3D plots, though wolfram's can: http://www.wolframalpha.com/input/?i=x%5E2%2By%5E2
On the other hand, google doesn't appear to take the extreme copyright stance that Wolfram Alpha does. Read their TOS: http://www.wolframalpha.com/termsofuse.html , specifically their Attribution and Licensing section. If you incorporate results from Wolfram Alpha in any work without attribution meeting their standards you will have breached your TOS and they suggest you also will have committed copyright violations…
They seem to have come with some nice algorithm to connect the graph dots. The problem: When you draw the graph using a naive formula putPixel(x, y(x)) you get isolated dots. Therefore you have to draw tiny lines between the points to get a nice smooth curve instead of isolated dots. But then there is the question of which points to connect – for example in tan(x) you can’t connect the last point on the ‘upper right…
One way is to set a threshold for whether or not to join the dots, if it's above the threshold perform a search between those points to see if they are between the dots or if they diverge, this search can be complicated or simple, google seems to use a fair bit of cpu power when zooming out on tan(x) so I'm guessing they're using a search here rather than some alternative 'clever' induction from the nature of the curve itself.
