More on Google Search: Graph Calculator!

You can now graph functions within Google Search! You just have to write "Graph for " and your favorite function. The interactive graph will appear at the top of the search results. You can zoom in and out, look at specific values of the plot in the plane, and move the graphic around, pretty much like you do with google maps. As you can see in the figure below, you can also plot several functions at a time. You just need to separate them with commas.

It's really cool, except that it doesn't work on the cellphone... They should release a graph calculator app! That would be like a slap in the face to Texas Instruments : P.

Here is the official Google link that announced it.
