# Exact Value of cos 27° We will learn to find the exact value of cos 27 degrees using the formula of submultiple angles. How to find the exact value of cos 27°? Solution: We have, (sin 27° + cos 27°)$$^{2}$$ = sin$$^{2}$$ 27° + cos$$^{2}$$ 27° + 2 sin 27° cos 27° ⇒ (sin 27° + cos 27°)$$^{2}$$ = 1 + sin 2 ∙ 27° ⇒...
