Trigonometry
- Definition of sin, cos, tan in right-angled triangle
- Value of trigonometric ratios with special angles (e.g. sin60°)
- Identities for sin (180°-x)=sinx etc
- Common Trigonometric identities (tan x = sin x / cos x etc)
- Solving simple trigonometric equations, e.g. 2sinx = 1 (note the required range for the angle)
- Sine and cosine formulas and their applications
- Heron’s formula for calculating area of a triangle (and also use cosine formulae and 1/2 absinC)
- Applications for Trigonometry (bearing, 3D figures etc)
