Common to all four courses, this content covers the foundational trigonometric ratios applied to right-angled triangles, as well as distances, midpoints and volumes and surface areas of standard three-dimensional solids. The unit circle is introduced to extend the definitions of cosθ and sinθ beyond acute angles, covering exact values at standard angles and the Pythagorean identity. In AA the unit circle and its quadrant relationships are developed at SL with formal treatment of the ambiguous case of the sine rule; in AI HL this material is an AHL extension.
