WebNov 24, 2015 · Break 11 into the largest factor of 12 >>> 6. This gives us 6pi/12 + 5pi/12 and the first identity can be written with 6pi/12 being simplified to pi/2 (90 degrees). So we have cos (11pi/12)=cos (pi/2 + 5pi/12) = cos (pi/2)cos (5pi/12)−sin (pi/2)sin (5pi/12) cos (pi/2) = 0 so the first term zero's out and sin (pi/2) is 1 leaving -sin (5pi/12 ...
