WebJan 2, 2024 · Cosine Difference Identity. For any real numbers A and B we have cos(A − B) = cos(A)cos(B) + sin(A)sin(B) Example 4.3.1: (Using the Cosine Difference Identity) Let us return to our problem of finding cos( π 12). Since we know π 12 = π 3 − π 4, we can use the Cosine Difference Identity with A = π 3 and B = π 4 to obtain. WebJun 21, 2024 · Find cos( π 12) by using trig identity: 2cos2a = 1 +cos2a In this case, 2cos2( π 12) = 1 +cos( π 6) = 1 + √3 2 = 2 +√3 2 cos2( π 12) = 2 + √3 4 cos( π 12) = √2 + √3 2 ( cos( π 12) is positive) Finally, cos( 11π 12) = − cos( π 12) = − √2 + √3 2 Answer link

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 ...
