Wolfram|Alpha introduces a fundamentally new way to get knowledge and answers—

not by searching the web, but by doing dynamic computations based on a vast collection

of built-in data, algorithms, and methods.

**PART 3 : Lets look at the mathematical searches and plotting**

**The following is not intended to be a handbook,**

but only a listing of search examples
