So, sin x + π 2 = sin x · cos π 2 + sin π 2 · cos x = sin x · 0 + 1 · cos x ∵ cos π 2 = 0 and sin π 2 = 1 = cos x. Hence, sin ( x + π 2) = cos x. Suggest Corrections. Free math problem solver answers your algebra, geometry, trigonometry, calculus, and statistics homework questions with step-by-step explanations, just like a math tutor. The value of sin pi/12 in decimal is 0.258819045. . .. Sin pi/12 can also be expressed using the equivalent of the given angle (pi/12) in degrees (15°). ∴ sin pi/12 = sin π/12 = sin (15°) = (√6 - √2)/4 or 0.2588190. . . For sin pi/12, the angle pi/12 lies between 0 and pi/2 (First Quadrant ). Since sine function is positive in the ....
