Students will be able to
- use de Moivre’s theorem to find multiple-angle formulae,
- use de Moivre’s theorem to find expressions for the powers of trigonometric identities,
- use de Moivre’s theorem to find trigonometric identities that are used to evaluate trigonometric integrals and solve trigonometric equations.
Students should already be familiar with
- the binomial theorem,
- trigonometric and exponential forms of complex numbers,
- de Moivre’s theorem.
