Covered in AA SL, AA HL and AI HL, this content addresses the solution of trigonometric equations in a finite interval, both graphically and analytically, including equations that reduce to quadratics in sinx, cosx or tanx. The Pythagorean identity and double angle identities for sine and cosine are applied. In AA this is SL content; in AI it is an HL extension where the unit circle provides the foundation and graphical methods are emphasised. The general solution of trigonometric equations is not required in either course.
