Answer
The difference between two angles of the cosine function is the cos of the first angle multiplied by the cos of the second angle and the sum of the sin of the first angle and sin of the second angle in it.
Work Step by Step
We have to write the identity into words using simple language. The difference of two angles of the cos function identity can be written as the cos of the first angle multiplied by the cos of the second angle and the sum of the sin of the first angle and sin of the second angle. The first angle may be denoted as $\alpha $ and the second angle can be $\beta $.
