Answer:
It is true, because the cosine function has a period of 2π
Step-by-step explanation:
Since, the period of the cos function is 360° ( or 2π radians ), it holds the property of:

Taking
as
,
is equal to 
The equation is true!
<u>Note:</u> The cos function is even function
Hence, the equation is true, because the cosine function has a period of 2π, NOT because the cosine function is ODD, which it is not!!
The correct answer is C. :)
<D because if you look at the angle it is <D
Step-by-step explanation:
step 1. when you graph 2 lines they must intersect unless they are parallel (same slope)
step 2. if they intersect then they have one point in common
step 3. that point in common solves both equations
step 4. when a point solves both equations it is called the solution.
