Sec 60° = 1/cos 60°. Method 2. By using the value of cosine function relations, we can easily find the value of sin 120 degrees. Using the trigonometry formula, sin (90 + a) = cos a, we can find the sin 120 value. As given, sin (90° +30°) = cos 30°. It means that sin 120° = cos 30°. We know that the value of cos 30 degrees is √3/2. Therefore, sin 120° = √3/2. Explanation: For sin 135 degrees, the angle 135° lies between 90° and 180° (Second Quadrant ). Since sine function is positive in the second quadrant, thus sin 135° value = 1/√2 or 0.7071067. . . Since the sine function is a periodic function, we can represent sin 135° as, sin 135 degrees = sin (135° + n × 360°), n ∈ Z. Method 2. Another method to derive the value of sineo 120 degrees is by using cosine functions. With the help of the trigonometry formula, sino (90 + a) = coso a ,we can determine sin 120 exact value. As we know, sino (90° + 30°) = sino 120 degrees. Hence, sin 120 degree = cos 30°.The difference between iniquity and sin is that the former refers to the unfairness or unjustness of a person’s wrong actions while the latter is all about the actual wrong actions.
