WebExplanation: For cos 60 degrees, the angle 60° lies between 0° and 90° (First Quadrant ). Since cosine function is positive in the first quadrant, thus cos 60° value = 1/2 or 0.5. Since the cosine function is a periodic function, we can represent cos 60° as, cos 60 degrees = cos (60° + n × 360°), n ∈ Z. ⇒ cos 60° = cos 420° = cos ... WebJun 23, 2011 · or. Note: We could also find the sine of 15 degrees using sine (45° − 30°). sin 75°: Now using the formula for the sine of the sum of 2 angles, sin ( A + B) = sin A cos B + cos A sin B, we can find the sine of (45° + 30°) to give sine of 75 degrees. We now find the sine of 36°, by first finding the cos of 36°.
