How to use WolframAlpha

There is a newer website called Wolfram Alpha that has gone public--

and has been compared to Google or even Wikipedia--but in actuality

it is not meant to do what either of those do.

Wolfram Alpha is a computational knowledge engine. It doesn't do rearches;

it does computations. In this article I will explain a bit about how it's used--

so that you can see if it is the right tool to gather the data you need.

     Since Wolfram Alpha computes answers, you must

     query it with something that can be computed.

     Here, for example, I asked it for the population of

     Los Angeles. It returned the number and built a graph

     showing population growth over several decades.

     I asked it about AT&T stock. I got a huge page of

     results, including the current price, the business

     fundamentals about the company, recent returns,

     a price history, performance and comparisons,

     a daily return analysis, future projections and more.

     Wolfram Alpha does math, of course, even calculus.

     I didn't know how to ask it something about calculus,

     but I gave it a simple equation to solve.

     You can compare items with a forward slash (/) between

     them. For example, I typed GDP USA / China in the query.

     The results were expressed as an equation,

     a value and shown on a graph.

     You can also use a plus sign (+) between items. For example,

     I typed blue+red and got results showing the color created by combining

     these two colors, along with a variety of ways to express the color mathematically

     in HTML. Complementary colors and a color triad were also given.
