Answer:
At every 360°
EG. -360, 0, 360...
Step-by-step explanation:
SEE ATTACHMENT
Simplify the equation by dividing by 2.
Convert the equation so both terms have the same denominator - cos(x).
Multiply both sides by cos(x).
Looking at the graphs, where the top one is y = sin(x) and the bottom is y = cos(x), you can see that at every 360°, 1 + sin(x) = cos(x)
EG
1 + sin(-360) = cos(-360)
1 + 0 = 1
