Web9 nov. 2015 · I tackle questions like this in 3 steps: 1) Apply De Moivre's Theorem 2) Use Pascals Triangle (Proves quicker for me than the method of Binomial Expansion) 3) Know your Trig Identities because this is where you're headed My working so far: ( cos θ + i sin θ) 3 = ( cos 3 θ + i sin 3 θ) By De Moivre's Theorem WebFirst write sin 3 θ as sin ( θ + 2 θ), and use the sine of sum formula. Then write cos 2 θ as 1 − 2 sin 2 θ and sin 2 θ as 2 sin θ cos θ. From there, use cos 2 θ = 1 − sin 2 θ, and simple algebra gets you the rest of the way.
