This IB Maths AA HL AHL 1.14 – Complex Roots and De Moivre’s Theorem resource introduces students to conjugate roots in polynomials with real coefficients and develops their understanding of powers and roots of complex numbers using De Moivre’s theorem. It builds confidence in moving between Cartesian and polar form, applying rational exponents, and finding all roots of complex numbers accurately.
Structured examples and practice tasks guide students through key skills, including using the conjugate roots theorem, solving polynomial problems with complex roots, and expressing answers in both polar and Cartesian form. The resource also highlights common exam mistakes, helping students avoid errors such as omitting conjugate roots, using incorrect arguments, or giving only the principal root.
With clear explanations, exam-style questions, and a full answer key, this resource supports HL students in building fluency with complex roots and De Moivre’s theorem in line with IB Mathematics AA expectations.
