Trigonometry and measure of angles
Trigonometry with acute angles
  • Apply trigonometry to solve problems involving right-angled triangles in two dimensions, true and compass bearings, and angles of elevation and depression

Trigonometry with angles of any magnitude
  • Represent angles of any magnitude using rays from the origin in the Cartesian plane and describe how one ray represents infinitely many angles

  • Use graphing applications or geometric construction to examine the ambiguous case of the sine rule, in which there are two possible solutions for an angle, and the condition for it to arise

  • Apply the sine rule, cosine rule and formula for the area of a triangle to solve problems where angles are measured in degrees, or degrees and minutes

Radians
  • Solve problems involving arc lengths and areas of major and minor sectors and segments
