Math 20B: Chapter 8, Further Applications of Integration - Videos

By Tracie Catania

Section 8.1:  Length of a curve

This video is an introduction to the topic and includes a challenging example at the end.  

Note:  in the example I forgot the right side of the absolute value just before I plugged in the limits of integration.  Sorry!

Note:  at about the 5 1/2 minute mark I forgot to close my parentheses!  It happened when I factored out the delta x on the right hand side.  Maybe I should remake the video now that I have two errors to fix.
