How come nothing happens when I click on an Evaluate or Interact button?
Something did happen. (You need to scroll down to see it.)
You've lost (or don't have) a connection to the Sage server. (Check your network settings or try again later.)
The Sage server is down. (Try again later.)
The button is not live -- it's just a screenshot. (Look more carefully
at the surrounding text.)
Prof. Smyth coded the page incorrectly. (Presumably unfixable.)
Why are there references to Sage cells which don't appear?
Javascript, which is used to embed Sage cells in webpages, is disabled in your browser. (Try enabling it.)
Your browser is using a dated version of Javascript. (Try updating.)
The browser you're using doesn't support Javascript. (Try another browser.)
How come I see gibberish like ${\displaystyle \lim_{x\rightarrow 1}3x+2}$ in places where I'd expect a mathematical expression?
LaTeX commands embedded in the page you're viewing are not being
typeset by MathJax as desired since...
Javascript, on which MathJax is based, is disabled in your browser. (Try enabling it.)
The browser you're using doesn't support Javascript. (Try another browser.)
You don't have a connection to the MathJax server. (Check your network settings or try again later.)
The MathJax server is down. (Try again later.)
Sometimes tweaking a slider or changing the value in an input box in a Sage interact causes the updated results to scroll off screen. This is annoying. Is there a workaround?
Try putting your browser in fullscreen mode. (On many systems the F11 key will toggle between fullscreen and normal mode.)
Is there a better way to save my CAS-generated graphics than taking screenshots?
Instead of (or in addition to) this TechCompanion I'd like to follow a CAS tutorial whose organizational principle derives from the CAS's syntax rather than from Cooper's Calc 1 syllabus. Do you have any recommendations?
