Theorem: DeMoivre's Theorem

(cos θ + i sin θ)ⁿ = cos(nθ) + i sin(nθ)

Maharashtra State Board: Class 12

Formula: De Moivre’s Theorem (Formulas)

Negative Powers

(cos θ + i sin θ)⁻ⁿ = cos(nθ) − i sin(nθ)

Conjugate Form

(cos θ − i sin θ)ⁿ = cos(nθ) − i sin(nθ)

Reciprocal Form

\[\frac{1}{\left(\cos\theta+\mathrm{i}\sin\theta\right)^1}=\cos\theta-\mathrm{i}\sin\theta\]

\[(\cos\theta-\mathrm{i}\sin\theta)^{-\mathrm{n}}=\cos\mathrm{n}\theta+\mathrm{i}\sin\mathrm{n}\theta\]
