Key Topics to Revise
1
Angles and Their Measurements
- An angle is formed by the rotation of a ray about its initial position
- Positive angles are measured anti-clockwise, negative angles clockwise
- Two main systems: Degree measure (360° = one complete revolution) and Radian measure
2
Trigonometric Functions and Their Properties
- Six trigonometric functions: sine, cosine, tangent, cotangent, secant, cosecant
- Primary functions are sine, cosine, and tangent; others are reciprocals
- Domain and range vary for different functions
3
Trigonometric Identities and Allied Angles
- Allied angles have sum or difference as multiples of π/2
- Functions of allied angles follow specific patterns based on quadrant
- Co-function identities relate complementary angles
4
Addition and Subtraction Formulas
- Addition formulas express trigonometric functions of sum/difference of angles
- These are fundamental for deriving other identities
- Double and triple angle formulas are special cases
