MAT 110 Lecture Notes - Lecture 16: Precalculus
Document Summary
Provide a generalization to each of the key terms listed in this section. 1. 1 sin sin sin sin = [cos ( ) cos ( + )] = cos ( ) cos ( + ) 1. 2 cos cos cos cos = [cos ( ) + cos ( + )] = cos ( ) + cos ( + ) 1. 3 sin cos sin cos = [sin ( + ) + sin ( )] = sin ( + ) + sin ( ) 1. 4 cos sin cos sin = [sin ( + ) sin ( )] = sin ( + ) sin ( ) 2. 1 sin + sin sin + sin = 2 sin(cid:18) + . 2. 2 sin sin sin sin = 2 cos(cid:18) + . 2. 3 cos + cos cos + cos = 2 cos(cid:18) + . 2. 4 cos cos cos cos = 2 sin(cid:18) + .
