Addressed at HL in both AA and AI, this content extends vector knowledge to lines and planes in two and three dimensions. Students work with vector, parametric and Cartesian equations of lines, find angles between lines, and determine whether lines are coincident, parallel, intersecting or skew. In AA HL the scope extends further to include vector and Cartesian equations of planes, angles between lines and planes, and the intersection of two or three planes — linking closely to systems of linear equations. In AI HL the focus is on modelling linear motion with constant velocity, finding positions and intersections, and working with variable velocity in two dimensions, including projectile and circular motion as special cases.
