Addressed in AA HL, AI HL and AI SL, systems of linear equations in up to three unknowns are solved using a range of methods depending on the course. In AI SL, technology is used to find unique solutions. In AI HL and AA HL, students work with cases involving unique, infinite and no solutions, interpreting these geometrically as intersecting, coincident or parallel planes. AA HL requires algebraic methods including row reduction, while AI HL connects this content to matrices and the inverse matrix method.
