The image depicts a right triangle ABC with angles 6 theta and 4 theta. (ii) Express sin A cos C into the sum of trigonometric functions using the following ... - sin a cos + cos a sin A. and from triangle CDB, sin sin (a-,) 1 b acos3-bcosa 2R or. a b sin (a -,B) = 2R cos -2R cos a,. = sin a cos - cos a sin ,B. The Law of Cosines (also called the Cosine Rule) says: c 2 = a 2 + b 2 − 2ab cos(C) It helps us solve some triangles. Let's see how to use it.
