Simplify
(1- cose0)(1 + cose0)
(1-sin0)(1+sin0)

(1- cose0)(1 + cose0) = 0

(1-sin0)(1+sin0) = 1

Step-by-step explanation:

(1- cose0)(1 + cose0) = 0

1st Simplify: \left(1-cos(0))(1+cos(0))

2nd Use the following trivial identity:     (0\right)=1

        =(1-1)(1+1)

3rd Simplify:(1- cose0)(1 + cose0)  = 0

(1-sin0)(1+sin0) = 1

1st Use the following trivial identity:      sin(0)=0

     (1 - 0) (1 + 0)

2nd Simplify: (1-sin0)(1+sin0) = 1
