问题
If you make a search at google.com for a mathematical equation google will in most cases automatically plot it for you.
For example, you can type in sin(x)/x or even a comma separated list such as sin(x)/x, cos(x), x to plot multiple functions on the same graph.
I know there's other Javascript plotting libraries, and I know that google offers other apis for charting, maps, etc. So does google offer an api or way to embed this math plotter into other sites/applications? I wasn't able to find any specific information about the plotter.
