Cos Cos 1 7pi 6=5pi/6 least value cos^-1(cos(7pi/6))=cos^-1(cos(pi+pi/6))=cos^-1(-cos(pi/6))=cos^-1(cos(pi-pi/6))=cos^-1(cos(5pi/6))=5pi/6 The principal value is in the second quadrant given here by the minus sign and k 1 The answer will be 5pi 6 You can write 7pi 6 as pi pi 6 Thus we can clearly see the angle falls in the third quadrant And the cosine value in third quadrant is always negative Hence cos pi pi 6 cos pi 6 coming back to the question cos 1 cos
