Summer Assignment chapter 1 video links

If you are having questions about the problems or level of  detail you should be getting in your answers these videos may give you some help. 

Using the videos….

     why did you go so fast over these problems?    
              I tried to make the entire assignment fit into two videos of less than ten minutes to fit onto YouTube.

              I also tried not to dwell too long on any one problem so you could get help on all of them
                      without needing to watch a 4o minute video.  

              Watch the video, fast forward, stop and watch a section again.  That is how you can benefit from these videos
