Example 4.4.1. A simple derivative with Alpha.
Use Wolfram|Alpha to find the derivative of \(x^3+5x+7\text{.}\)
Solution.
When you call the website, you get an input bar much as you would with your favorite search engine.

The interface for Wolfram|Alpha is rather robust. While Wolfram|Alpha lets you use a Math Input pallette, we can ask the question in plain English. In our case, we would like to find the derivative of \(x^3+5x+7\) with respect to \(x\text{.}\) Some of the ways of asking that question are:
-
find the derivative of (x^3+5x+7)
-
find the derivative of (x^3+5x+7) with respect to x
-
derivative of (x^3+5x+7)
-
differentiate (x^3+5x+7) with respect to x
-
differentiate (x^3+5x+7)
-
D (x^3+5x+7)
-
d/dx (x^3+5x+7)
-
(x^3+5x+7)โ
For all of these, the website provides the same answer.
