Before we start taking derivatives of log functions, it would be a wise decision to review their three basic properties. In this Warm-Up Exercise, use those properties to expand or condense two logarithmic expressions. Duration: 6:37

After formally defining a logarithmic function, we will use implicit differentiation to derive a derivative rule for ln(x). Duration: 7:40

Example 2 presents us with four opportunities to put our new derivative rule into practice. Duration: 5:22

On Example 3, we have two slightly more complicated functions, whose derivatives require the use of the log and chain rules. Duration: 2:13
