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.
