Need help using De Moivre's theorem to write cos4θ & sin4θ as terms of sinθ and cosθ. … WebLearn about the relationship between the sine & cosine of complementary angles, which are angles who together sum up to 90°. We want to prove that the sine of an angle equals the cosine of its complement. \sin (\theta) = \cos (90^\circ-\theta) sin(θ) = cos(90∘ − θ) [I'm skeptical. Please show me an example.] Let's start with a right triangle.
