iPad: Class notes, from webpage -> taking notes

My 211 class notes webpages require that you be on campus or (from off campus) logged in. Unfortunately this keeps you from being able to use Safari's share icon to send a web page to Notability.

But with just a few more step you can do it: This article shows you how. The outline is...

1. While you're looking at a web page in Safari, take a screenshot on your iPad.
2. A smaller thumbnail image of the webpage shows up in the lower-left of your screen.
3. Click on that, and select "Full Page" instead of Screen,
4. Then you can either...
   • Choose the 'markup' icon to edit the picture of the whole page within "Pictures". -OR-
   • Choose the 'share' icon at this point and send the whole web page to Notability.

Using show(...) for trouble-shooting

Sometimes it's not so obvious when or where parentheses are needed. show(...) displays an expression rendered in math mode.

For example, I'd like to evaluate $$\color{blue}{e^{2\pi}}.$$
