Audio clips:

limit-idea.mp3:  There should be a button on the web page at Definition 1, on limits-intro.html.  They just play the audio this time.  

limits-basic-sol-5.mp3: Step through the files limits-basic-sol-5-[1-5].html, then finally limits-basic-sol-5.html as the audio plays.

Start with 5-1

After "factor both the numerator and denominator", go to 5-2
After "The next theing we do, is cancel out...", go to 5-3
At "by simply evaluation", go to 5-4
At "go through the arithmetic"  go to 5-5
At "it comes out to be" go to 5.

Now, the relevant places on the equations should match up so that what is being talked about appears on the screen, not requiring them to scroll; I guess it's clear where the pointer should be.
