WebSin 11pi/6 Using Unit Circle. To find the value of sin 11π/6 using the unit circle: Rotate ‘r’ anticlockwise to form 11pi/6 angle with the positive x-axis. The sin of 11pi/6 equals the y-coordinate (-0.5) of the point of intersection (0.866, -0.5) of unit circle and r. Hence the value of sin 11pi/6 = y = -0.5. WebMar 29, 2014 · 7 years ago. You have to know that sin (30 degrees) = sin (pi/6) is 1/2. This is the only trig function you have to memorize. Then, from the Pythagorean theorem, cos (30) is rt (3)/2. You can figure out sin (45) (see this video). From these you can get all the 12 simplest angles on the unit circle (8 multiples of 30 deg, 4 multiples of 45 (plus ...
