Wolfram|Alpha is a useful tool in teaching mathematics or doing research. It can do math computations as well as answer factual questions like, “what is the population of Chicago?” The company introduced two add-ons for Google Drive to harness the power of W|A within Google Docs and Google Sheets. Here at the links to get them installed:
Once installed, in a Doc or a Sheet, go to the menu bar › Add-ons › Wolfram|Alpha for Docs or Sheets › Open Wolfram|Alpha Sidebar.
From here, you can use Wolfram|Alpha as you would do on the website. The neat thing is you can copy and paste the results from the sidebar into the document you are working on.
If you use both Google Drive and Wolfram|Alpha (and if you don’t, I recommend you do), these are two invaluable tools combined in one place.
