Therefore, the exact value of cos 30 …, To find the value of tan 150 degrees using the unit circle: Rotate ‘r’ anticlockwise to form 150° angle with the positive x-axis. The tan of 150 degrees equals the y-coordinate (0.5) divided by x-coordinate (-0.866) of the point of intersection (-0.866, 0.5) of unit circle and r. Hence the value of tan 150° = y/x = -0.5774 (approx)., Or you can say, the Sine of angle α is equal to the ratio of the opposite side (perpendicular) and hypotenuse of a right-angled triangle. The trigonometry ratios sine, cosine and tangent for an angle α are the primary functions. The value for sin 45 degrees and other trigonometry ratios for all the degrees 0°, 30°, 60°, 90°,180° are ...
