Taking a Look at Wolfram|Alpha
Lets take a small break from learning and look at a somewhat new tool. Wolfram|Alpha is a “computational knowledge engine that draws on multiple sources to answer user queries directly.” While this tool has numerous applications, I will take a look at how it can be used for math.
Simply by entering a number, you will gain access to a variety of information about it. It includes some information about the number in different forms such as a Roman numeral or binary. More useful information may be found in its prime factors or its properties. Other information is included which would be useful to some individuals.
Now, onto a more interesting application. Wolfram|Alpha accepts functions as input. The first thing noticed is that Wolfram|Alpha will graph the function. Then it will provide you with the figure of the base function. With the inclusion of the roots of the graph, this basic information may all that is needed.
The other information returned is what I find to be the most valuable. Not only does Wolfram|Alpha take the derivative of the function as well as the integral, but it also will show the steps it took to reach its answer.
Evidently, Wolfram|Alpha has some potential. I encourage you to tinker with different functions in it. Also, try putting some of the functions on this site into the engine. For many more examples visit this link.
