As Example 7 demonstrates, sometimes it is advantageous to apply one or more properties of logarithms prior to taking the derivative. Doing so will allow us to simply the derivative process, often avoiding the product or quotient rules. Duration: 5:40

While the previous example did an adequate job of motivating the use of log properties, Example 8 demonstrates just how much time and anxiety such a technique can save you. Duration: 2:53

There is, of course, a domain limitation for logarithmic functions, since you can't take the log of a negative number. We can expand that domain by including absolute value brackets inside the logarithm. The question is, how does that affect the derivative? Duration: 4:41

At less than one minute, perhaps the video should have appeared at the end of the previous one. Maybe I'll edit them together if I can get 1,000 likes on this video. Duration: 0:53
