Differentiation I can differentiate natural logs ln (x) Learning objectives I can differentiate natural logs ln (x)

This is what we use  so let the games begin . . . . . . . . . . .

Compound Functions Involving logs We can always use the chain rule to differentiate compound log functions. However, the first 3 log laws can simplify the work. It’s important to use these laws as they change compound functions into simple ones.

Exercises Differentiate the following with respect to x: 1. 2. 3. 4. 5. Solutions: 1. 2.

Exercises 3. 4. 5.

and now for the sheets and the book so we can do loads of yummy practice.
