**Trigonometry**

**Functions**

This section is mainly directed to IB Diploma students. I have tried to indicate after each headline what level it is directed towards. [Stu/SL/HL]. If there is no such indication then it should be suitable for all levels.

(A slightly different approach to this topic can be found in the Algebra section. )

- Functions and the function notation
- Functions, Quiz 1
- Various definitions, the graph of a function and the range and domain.
- Composite functions
- Functions, Quiz 2, composite functions
- Functions from tables and graphs
- Quadratic functions – an interactive page.
- Rational functions in the form
*f*(*x*)=*p*/(*cx*+*d*)+*q*– an interactive page.

- Rational functions in the form
*f*(*x*)=(ax+b)/(cx+d) – an interactive page.

**Derivatives**

**Integration**

Up a level : High school, secondary school, IB DP related.
