I lost power at about 4:00 minutes in, so that is why there is a 25 second blank period in the middle of the video.

There is an error on FRQ #5.  The asnwer should be -2/3 and I said -1/3.  All the work shown in the video is correct, I just had a brain fart and wrote -1/3 instead of -2/3.  My bad.
