Learning objectives
I can differentiate natural logs ln (x)

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

4. 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.

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

6. Exercises 3. 4. 5.

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

8. Success Criteria
