WebTo find the value of cos π/12 using the unit circle: Rotate ‘r’ anticlockwise to form pi/12 angle with the positive x-axis. The cos of pi/12 equals the x-coordinate (0.9659) of the point of intersection (0.9659, 0.2588) of unit circle and r. Hence the value of cos pi/12 = x = 0.9659 (approx) ☛ Also Check: cot pi/3 cos 7pi/6 sin 3pi/2 cos 3pi/4 WebThe sine is a trigonometric function of an angle, usually defined for acute angles within a right-angled triangle as the ratio of the length of the opposite side to the longest side of the triangle. In the illustration below, sin (α) = a/c and sin (β) = b/c. From cos (α) = a/c follows that the sine of any angle is always less than or equal to one.
