You can now customize your Wolfram Alpha (W|A) queries using a W|A widget right on your web site. It’s currently in the Beta stage. You’ll see a widget,which I cooked up in a few minutes, below this post. I was able to control the output to just what I wanted. I did not need all sorts of complex number representations and other stuff that comes with the standard W|A query for a simple derivative. Also, with the widget, you don’t leave the web site you’re on. I plan to put some of these on my class web pages.
Here’s another one.
