What is Trigonometric Identities for A±B about?

The document provides trigonometric identities for the sine and cosine of the difference and sum of two angles, A and B. It includes formulas for sin(A-B), cos(A-B), tan(A-B), cot(A-B), cosec(A-B), and sec(A-B), as well as their counterparts for sin(A+B) and cos(A+B). Additionally, it presents the products sin(A+B)sin(A-B) and cos(A+B)cos(A-B) in terms of sine and cosine squared functions.
