Find an exact value.<br><br> <img src="https://tex.z-dn.net/?f=cos%28-%20%5Cfrac%7B%20%5C77%20%5Cpi%20%20%20%20%7D%7B12%7D%29%20

\cos\left(-\dfrac{7\pi}{12}\right)=\cos\dfrac{7\pi}{12}

Recall that

\cos^2x=\dfrac{1+\cos2x}2

Let x=\dfrac{7\pi}{12}, so that

\cos^2\dfrac{7\pi}{12}=\dfrac{1+\cos\dfrac{7\pi}6}2=\dfrac{1-\dfrac{\sqrt3}2}2=\dfrac{2-\sqrt3}4
\cos\dfrac{7\pi}{12}=\pm\sqrt{\dfrac{2-\sqrt3}4}=\pm\dfrac{\sqrt{2-\sqrt3}}2

Since the angle \dfrac{7\pi}{12} lies in the second quadrant, you know that the cosine must be negative, so

\cos\dfrac{7\pi}{12}=-\dfrac{\sqrt{2-\sqrt3}}2
