Webtan (18°) = √ (25 − 10√5)∕5. – – – To find sin (36°) we can use the double angle formula sin (2𝑥) = 2 sin (𝑥) cos (𝑥) ⇒ sin (36°) = 2 sin (18°) cos (18°) = 2 (√5 − 1)∕4⋅√ (10 + 2√5)∕4 = (√5 − 1)√ (10 + 2√5)∕8. Again, squaring both sides allows us to get a neater result: sin² (36°) = (6 − 2√5) (10 + 2√5)∕64, simplifying to (10 − 2√5)∕16.
