Answer 2

The expression you provided is:

cos(180 - α) + cos(α)

To simplify this expression, you can use the trigonometric identity:

cos(180 - θ) = -cos(θ)

So, applying this identity to the expression:

cos(180 - α) + cos(α) = -cos(α) + cos(α)

Now, notice that the two cosine terms with α cancel each other out:

-cos(α) + cos(α) = 0

So, the simplified expression is 0.
